I love this guy's voice! Most people are extremely boring to listen to when given scientific subjects, but this guy has the sort of voice that one can listen to hours for. Great video Brian!
Say that again. Very good voice and intonation indeed. I also follow an Australia based guy who has tons to tell about electronics. Very very interesting but after half an hour you end up all wind up.
+Kurt Schatteman I think I know the Aussie you're talking about but I forgot his name. All I can remember is he dissembles things like meters and did a tour of a TV transmitter. If that's the same person could you please let me know his channel name. Thank you.
Whilst the channel is small, the content is huge! I love your videos, they're incredibly informative and terribly interesting! Thanks for taking the time to make these! I really appreciate it!
Brainiac75 pleas help i am buying 10 pieces of neodymium magnets and and i am being asked about the dimensions so what is the best i am a 1st time user?
+ Omar Taman Hi, you're asking for something I give you guidelines for in this video you have commented on? To sum it up: go for a cylinder magnet that isn't very thin and don't go over 20 mm in diameter for your first magnet.
As a diesel mechanic who has worked on gigantic generators that started my career selling and installing upgrades for cars and trucks I can really appreciate the magnet/Ferrari analogy. I was watching this video with my 7 year old who wants to get some magnets because of this channel and you immediately won me over lol.
Very wise advice even after all these years I still get bit from time to time. Many blood blisters in my past. So when a friend casually passed a disc magnet the size of my palm and 2 inches thick to me he was amused by the seriousness and respect with which I handled it.
I bought some neodymium magnets that are about 1cm wide and .5cm thick and even when these come together it's hard enough to hurt quite a bit when it pinches my skin. It's also nearly impossible to separate them by brute force, without sliding them past one another. Not to mention how many uncoated magnets I've shattered into dozens of tiny, razor sharp pieces by accidentally letting them snap together. It takes a LOT of vigilance to handle even small magnets like that properly. I couldn't imagine a "monster" magnet.
I bought a variety of neodymium magnets, the largest having a 405 pull. Following your advice, I began experimenting with the very smallest, a 39 pound pull, 1 inch cup magnet. I have experience with very large ceramic magnets, so I had great confidence. I now have a small blood blister on one finger, and a greater respect for magnets. Had I ignored your good advice, I could well have had a crushed finger with the largest magnet. Thanks for your fine advice.
My first try is a 1cm disc I bought from a hardware store and I love it. It's so versatile because of the small size, I can use on everything and carrying it to everywhere easily.
I took my driving test in a Cadillac. You might not think of those as being tough for beginners to drive, but they are. Not because they're fast or squirrely, but because they're HUGE. They're expensive too, especially the older ones.
Once again a really nice video. Allthough I' ve got over 2000 neodymium magnets in different shapes and sizes( mostly 5mm balls), it's also a guide for me. Sorry for my bad English and spelling mistakes, I am German.
Magik Max Thank you! The 5 mm spheres are very popular and with thousands of them you can make nice shapes and sculptures :) And your English is good - no problem.
I've only just come across your videos and of course was immediately off to buy the largest Neodymium magnet I could find.... Then I saw this video.. .Perfect! I then realised I would be making a mistake and set my sights on the Z-13 set as you've shown here. Alas, the 2 companies I've seen you show in your videos deliver outside europe so I'm now off to see if anyone local (Australia) has them. They probably will, at double to triple the price alas. Great videos, informative and interesting, keep em up.
+Terry Wood Thanks! And yes, shipping neodymium magnets intercontinentally is not easy/cheap. They are only allowed on airplanes in well-shielded boxes. I know nothing about the Australian market - good luck with it :)
Gristle Von Raben You can also find some that are zinc-plated. They're very resistant to corrosion too, without being as expensive as gold-plated ones.
Gristle Von Raben You're welcome :)FlipUltraHD's advice about the zinc-plated magnets is a good advice. The 4-layer coatings like Ni-Cu-Ni-Epoxy or Ni-Cu-Ni-Au have so thin layers that even tiny scratches will expose the nickel underneath.
I leaned the bite of these magnets as a kid. Going to the scrap yard with my dad. The office guy gave me a pair of magnets that were supper strong. I was playing with them in the truck on the way home putting one on each side of my arm. They slipped real quick and gave me a nasty pinch. My dad had to pull the truck over to help get them off 😂 I ended up breaking the magnets a few days later letting them crash together
Hey thank you very much, Brian!!! :D I was able to finally buy my first Neodymium Magnet! Im just a beginner, and thats why im very thankful that youve made this video! By the way i was youre 300,000th subscriber! :)
He was so true. I bought two 20x20x10 square neodymium magnet. and I tried to seperate. Neodymium magnet was so strong. neodymium magnets pinched my skins with sharp corners. that was so hurt :( So buy MUCH SMALLER than YOU THINK. and I need to learn grammar
In my opinion, a long cylinder would be best for a beginner. They are easy to handle because they have a lot of room to hold on to, and can be most easily controlled when letting it contact another magnet or metal surface. I like cubes and blocks for how they look but a long cylinder is most easy to casually play with. I carry a .5x2 inch cylinder magnet with me and it handles pretty nicely. Though do be careful what you set on your lap when carrying a magnet around, I almost ruined my laptop fan once.
+KingofHearts67 Cylinder magnets are the easiest to handle, no doubt about it. I just have trouble with recommending them since you pay for a lot of length of magnet that is not really adding much power. A 10x40 mm cylinder magnet is 4 times more expensive than a 10x10 mm disc magnet. But it is far from 4 times as powerful, only around 20% more pull force... So measured in power a cylinder magnet is not good value for money. It's still a nice magnet though :)
If you don't mind a 3 or 4 week shipping time then EBay has a boatload of sellers with excellent prices. Most of them are from China and the finish of the magnets are usually not superb but you can get an N52 40x40x20mm square type or a 40x20mm round type for about $15 and shipping is free. The photos are not faked so at least you can see the finish quality and decide for yourself. I've purchased them from Chinese sellers on EBay and am quite satisfied! Sometimes the dimensions are a bit off. Like maybe you will order a 40x40x20mm magnet and when you get it it's actually 41x37x19 - but hey, that pretty close. And also so far my gauss meter says they are within one rating of what was specified. So if it says N50 on the seller's description then it could be N48 or it could be N52. But in all honesty there is almost no difference between N44 and N52 for example. You can't tell and even the gauss meter has trouble, lifting power is the difference between something like 190kg and 200kg.
Actually there's is a cool magnet shop in my country, I usually buy little magnets from them. I just walk in, say what I want the magnet for and they can show me how they look, I can change my mind and pay. I don't buy much magnets but when I need some I know where to look :)
Since ca. a half a year I have a magnet in my finger. It's not very useful except for picking or holding up small screws. However you can feel electro magnetic fields with it which I find really interesting because sometimes you feel it in places you don't expect and in addition it's something a normal human doesn't feel.
Thank you for taking the time to make this educational video, especially the warnings. I myself really learned a lot by watching, i never really thought about how dangerous magnet's can be until i watched this video. Please be responsible everyone, and keep powerful magnet's out of reach of your children, if you have magnets that are strong enough to crush a grown mans hand, little fingers and toes don't stand a snow ball's chance in h3ll.
My pleasure. Small kids and large neodymium magnets is definitely a bad match. I also hope that people are responsible, so everyone is safe and large neodymium magnets are'nt banned.
@@TheRadioactiveBanana32 even Alnico is giving me pinch i bought disc magnets of 90 mm * 36 mm * 15 mm disc Alnico magnets and it's giving me pinch whenever i try to stick them together.😭
i bought some 20×15 cylinder magnet. i really underestimate their power until one if em start flying so fast and broke it. They are really strong people. like *really* strong
It just so happens that there are a few warehouses of neodymium magnet stores here in Texas where I am, in fact in the same town that I am in. I can literally go over to the place and buy magnets straight from the store. It is the Applied Magnets store. You may have heard of it. There is another one that I do not immediately remember. Applied magnets at one point sold 1/2 inch grade N54 magnets.
+QuestionXV Lucky you :) And yes, I did see the N54 magnets they advertised with. But they quickly stopped selling them - were they underspec or just a one-time offer? I don't know.
Here I am over a year later, I'm still amazed that I have one of the biggest neodymium warehouses in the world less than 15 miles from my house, I live in Plano and the warehouse is at 1111 Summit Ave #11, Plano, TX 75074, and there is another warehouse, the one for CMS Magnetics, 1839 Wall St, Garland, TX 75041. That should give some people here excuse to move to Texas, by the way, congratulations on almost 200,000 subscribers.
Gotten my set coming in the mail, followed majority of the guidelines you stated, probably somewhat of a slightly larger magnet (.56 in^3) but pretty close.
As long as you're prepared and don't start with slamming the magnets on a large piece of iron with your fingers between, you'll be fine :) Thanks for watching and good luck with the magnet.
Brainiac75 Well they arrived today, probably my happiness took away part of my preparation as putting them on a table and the magnets swiping around the area ends up two chips from two of them coming off. I decided to put the two that shattered away to keep them away from moisture so they don't corrode as quickly. Well thanks for the good luck, although maybe a shatter there's always plenty of time to get better handling the magnets. :)
i was sorta of beginner but i still bought 150x50 N45 disc-shaped neodymium magnet... and i can say it was a mistake... despite i clearly understood it's power i cant really handle it at home cause it attracts metal objects in 1 meter radius... however its fun cuz that thing can lift up to 100kg while being separated by 20 mm wooden table. Also throwing a metal grid on this beast with a apple on it slices it in little cubes in no time :)
Wow, Amazing video, I have a new found respect for magnets as I tinkered with a few smaller one's and still got BIT, I now know to be far more careful. I pulled apart several hard drives for their magnets and I am amazed as to how powerful they are I can not imagine the really large ones. But I digress... Great video, yes please do a video on the Super Magnets, as I know in my heart of hearts I fear them now and if you don't do such a video I will never know... I bought a water cooling kit, used, and it had these very thin, like almost paper thin, 1/16th of an inch or thinner then a typical coin, but they are very powerful as I use them to hold various tools like snipes and pliers. They must me Neo's because they are very strong, I might venture to say probably 48's, if they are 52's I am very impressed. Either way they are round and BIT. The Magnets pulled from hard drives are very powerful, surprisingly powerful to say the least and I left the metal attached to them as it seems to control their power a lot and makes them far easier to handle. Even with the attached metal shield they are still fun to play with, at least I know I will not crush my fingers with them where as if they are removed from their shields they will be very dangerous to handle. Thank for sharing this awesome video....
Paul Bialozor Hehe, yes they are surprisingly powerful. They seem so innocent until a large piece of metal comes close to them...Neo magnets from scrapped hard disk drives are a cheap solution. But opening the hard drives and removing the magnets from their brackets is not always easy. And the magnets are quite specialized (my video about them: th-cam.com/video/ep_VCotA1ZY/w-d-xo.html). But especially the really old hard drives can have some large impressive magnets. Thanks for watching and commenting!
I have several hundred small disk neodymium magnets that I used with model kits to hold parts that I wanted to be removable or changeable with other parts, and I will say even the tiny ones will bite you with some force if you let them.
Yep, once in a while even small magnets will remind you of how powerful they are ;) But not a permanent reminder like with the big ones :\ Thanks for watching!
thanks. i have been buying too thin and straight lined. All end up shattering. plus i need to mark the poles. Small thick disc for my next purchase. Tyvm
Can you make a video about the reasons for all the different types of magnet coatings and their uses? Zn, Ni, Au, Epoxy... Thanks! Great videos by the way!
Thanks! The different coatings have different properties, but for the average user they are only a matter of asthetics. For eaxmple, gold just looks good and has no practical purpose. Zink is a cheaper solution and good for people with nickel allergy, that shouldn't handle magnets with the standard nickel coating. Epoxy is better for protecting the magnet against moisture in the air, but still can't be submerged in water. For that you need teflon- or rubber-coated magnets, that are even suitable for saltwater.
1. Do you know where the magnets in the kits you show are manufactured? 2. Are magnets typically marked with the North and South poles on them? If no, why not?
I've just crushed the little one, trying to hold 1kg metal weight. and it wasn't 1mm x 10mm. It was 1mm x 5mm magnet, that could hold 1kg weight in the air.
Thank you!!!, I am looking at using this (disc type 15mmx3mm) to hold up 2 acrylic sheets frames for posters against the wall, hope it would hold its weight.
Thanks so much for your reply. I envision the storage of magnets, much like the storage of isotopes, where they store them in "bird cages" (If you Google, you will see what I mean) where the magnets are stored in a binary fashion, but not in close proximity. Perhaps there is more structural safety in such a binary approach? I wonder at what point do the materials break, and what if we just had just essentially a powder instead? Certainly, a mechanical system could be devised to variably bring many individual magnets closer together, and then seperate them. A simple PVC frame could be used to do that, provided that only smaller magnets were used. How far can you cause deflection of a compass with your large is something I wonder?
There's also first4magnets.com in the UK, they've got many kinds of magnets including the high-grade N52 ones. They don't have huge magnets, but their largest can lift 150kg, enough to mush your hands.
If you want to see what a magnetic field looks like in a ferrocell just click my icon. Hardly any body knows what a ferrocell is. simply it is 2 pieces of glass with ferrofluid between them and lit with LED lights. A magnet is placed close to the glass and a visual of the magnet field is seen. Its 3d too but you cant really see that in a video.
I recently upgraded to a 2" x 2" x 1" magnet after having two 3/4" diameter x 1" magnets for a long time, inspired by your videos :) Do you have any suggestions for what I might get next if I eventually get another one? (Or something particularly interesting to do with that size?) Really appreciate your videos!
Benrob55 Thanks :) Personally I would go for a 2" cube. The extra thickness makes it a very powerful magnet. But only buy such a monster if you have handled the 2x2x1 without any incidents ;)
@@karenmmcthree I have a 2x2x1” block and a 2” diameter x 1” disc. I didn’t end up getting a 2” cube (yet...). And I keep the block and the disc on opposite sides of the room haha.

I started off with a 1" cube N52 neodymium magnet. Max 140lbs of force. Seriously a dangerous toy.
i started off with baby 10*6 mm
and now i have 50*50*25mm
(death magnet by its nickname)
tho i bought the N35 version not N40 so it only 50kg not 100
I started with a 30x5mm N45 neodymium magnet that has 23kg pull force.
Well I saw a neodymium magnet with 116kg pull force certainly the most dangerous one
My magnet was the largest disc magnet the website that I used had. (I didn’t use supermagnete)
Very wise advice even after all these years I still get bit from time to time. Many blood blisters in my past.
So when a friend casually passed a disc magnet the size of my palm and 2 inches thick to me he was amused by the seriousness and respect with which I handled it.

In my opinion, a long cylinder would be best for a beginner. They are easy to handle because they have a lot of room to hold on to, and can be most easily controlled when letting it contact another magnet or metal surface. I like cubes and blocks for how they look but a long cylinder is most easy to casually play with. I carry a .5x2 inch cylinder magnet with me and it handles pretty nicely. Though do be careful what you set on your lap when carrying a magnet around, I almost ruined my laptop fan once.
+KingofHearts67
Cylinder magnets are the easiest to handle, no doubt about it. I just have trouble with recommending them since you pay for a lot of length of magnet that is not really adding much power. A 10x40 mm cylinder magnet is 4 times more expensive than a 10x10 mm disc magnet. But it is far from 4 times as powerful, only around 20% more pull force... So measured in power a cylinder magnet is not good value for money. It's still a nice magnet though :)
If you don't mind a 3 or 4 week shipping time then EBay has a boatload of sellers with excellent prices. Most of them are from China and the finish of the magnets are usually not superb but you can get an N52 40x40x20mm square type or a 40x20mm round type for about $15 and shipping is free. The photos are not faked so at least you can see the finish quality and decide for yourself. I've purchased them from Chinese sellers on EBay and am quite satisfied!
Sometimes the dimensions are a bit off. Like maybe you will order a 40x40x20mm magnet and when you get it it's actually 41x37x19 - but hey, that pretty close. And also so far my gauss meter says they are within one rating of what was specified. So if it says N50 on the seller's description then it could be N48 or it could be N52. But in all honesty there is almost no difference between N44 and N52 for example. You can't tell and even the gauss meter has trouble, lifting power is the difference between something like 190kg and 200kg.
You really need to make a video about the Macho set. Very interesting.

i was sorta of beginner but i still bought 150x50 N45 disc-shaped neodymium magnet... and i can say it was a mistake... despite i clearly understood it's power i cant really handle it at home cause it attracts metal objects in 1 meter radius... however its fun cuz that thing can lift up to 100kg while being separated by 20 mm wooden table. Also throwing a metal grid on this beast with a apple on it slices it in little cubes in no time :)
U dumbass
Great videos. Really well done on all I have watched so far.
Me who bought six N52 1-inch cubes to send a pinball into orbit: * walks away whistling*
Because of you im gonna buy a quality magnet. ty very much.
Wow, Amazing video, I have a new found respect for magnets as I tinkered with a few smaller one's and still got BIT, I now know to be far more careful. I pulled apart several hard drives for their magnets and I am amazed as to how powerful they are I can not imagine the really large ones. But I digress...
Great video, yes please do a video on the Super Magnets, as I know in my heart of hearts I fear them now and if you don't do such a video I will never know...
I bought a water cooling kit, used, and it had these very thin, like almost paper thin, 1/16th of an inch or thinner then a typical coin, but they are very powerful as I use them to hold various tools like snipes and pliers. They must me Neo's because they are very strong, I might venture to say probably 48's, if they are 52's I am very impressed. Either way they are round and BIT.
The Magnets pulled from hard drives are very powerful, surprisingly powerful to say the least and I left the metal attached to them as it seems to control their power a lot and makes them far easier to handle. Even with the attached metal shield they are still fun to play with, at least I know I will not crush my fingers with them where as if they are removed from their shields they will be very dangerous to handle.
Thank for sharing this awesome video....
Paul Bialozor Hehe, yes they are surprisingly powerful. They seem so innocent until a large piece of metal comes close to them...Neo magnets from scrapped hard disk drives are a cheap solution. But opening the hard drives and removing the magnets from their brackets is not always easy. And the magnets are quite specialized (my video about them: th-cam.com/video/ep_VCotA1ZY/w-d-xo.html). But especially the really old hard drives can have some large impressive magnets.
Thanks for watching and commenting!
brainiac75 Great to know, I have some very old Hard Drives, like 200 MEGs not GIGS, Megabytes... I look forward to dismantling them...
I found that recycled speakers do a great job. They are easy to get and are very powerfull.
I have several hundred small disk neodymium magnets that I used with model kits to hold parts that I wanted to be removable or changeable with other parts, and I will say even the tiny ones will bite you with some force if you let them.
Yep, once in a while even small magnets will remind you of how powerful they are ;) But not a permanent reminder like with the big ones :\ Thanks for watching!
Very very good. Cant give you enough thumbs for this one. Good advice, not lame choices.
gamingSlasher Thank you very much. Glad that you think I made a fair compromise between safety and power :)
With Great power comes great responsibility
Macho set! Do a Macho set video! MAKE MORE VIDEOS I LOVE YOUR VOICEOVERS AND SCIENTIFIC INPUT!
my first neodymium magnets are 20mm long and 4mm high n45 grade. those little magnets can pack a punch! but now i want a 10mm x 10mm neodymium magnet.
smallenginedude71 I can understand why. A 20 mm wide magnet only 4 mm thick will break easily :)
brainiac75 thanks for the reply!
i have indeed broke 7 out of the 20 magnets.
I bought an 30 x 10 disc magnet and 10x10x10 square magnet as my first neodymium magnets
This is a very helpful video I appreciate it!! Very in detail!
Hey, really really really useful video for mortals like me!!! Thanks a lot for the info!!!! You rock!!!
I like these magnets I want to get some more I have small ones. They can be really useful!
thanks. i have been buying too thin and straight lined. All end up shattering. plus i need to mark the poles. Small thick disc for my next purchase. Tyvm
Absolutely beautiful, Love your videos.
Thank you! :) your videos are super informative and helpful.
MACHO SET!
Got two n52 35x35x60mm magnets in the mail. Should be fun.
I bet the ring magnets would work great to ties a rope to, to use in deep water. My gramps used to have something like for ice fishing.
Can you make a video about the reasons for all the different types of magnet coatings and their uses? Zn, Ni, Au, Epoxy...
Thanks! Great videos by the way!
Thanks! The different coatings have different properties, but for the average user they are only a matter of asthetics. For eaxmple, gold just looks good and has no practical purpose.
Zink is a cheaper solution and good for people with nickel allergy, that shouldn't handle magnets with the standard nickel coating.
Epoxy is better for protecting the magnet against moisture in the air, but still can't be submerged in water. For that you need teflon- or rubber-coated magnets, that are even suitable for saltwater.
Go big or go home! Buying that monster behemoth N52 as my first!
I would recomend buckycubes as your powerful magnet
1. Do you know where the magnets in the kits you show are manufactured?
2. Are magnets typically marked with the North and South poles on them? If no, why not?
I bought 2 small 1mm x 10mm and 3mm x 10mm, 2 days ago. Those are weak, but good for attaching photos to metal surfaces.
Szklana147 Yes, they are a little too thin to do any heavy lifting :) But for photos they are more than enough.
I've just crushed the little one, trying to hold 1kg metal weight. and it wasn't 1mm x 10mm. It was 1mm x 5mm magnet, that could hold 1kg weight in the air.
Machinists magnetic base, very strong but you can keep them tuened off until they are in position.
Thank you!!!, I am looking at using this (disc type 15mmx3mm) to hold up 2 acrylic sheets frames for posters against the wall, hope it would hold its weight.
You're welcome. Magnets generally don't like shear forces. More info: www.kjmagnetics.com/blog.asp?p=how-much-will-a-magnet-hold
Thanks so much for your reply. I envision the storage of magnets, much like the storage of isotopes, where they store them in "bird cages" (If you Google, you will see what I mean) where the magnets are stored in a binary fashion, but not in close proximity. Perhaps there is more structural safety in such a binary approach? I wonder at what point do the materials break, and what if we just had just essentially a powder instead? Certainly, a mechanical system could be devised to variably bring many individual magnets closer together, and then seperate them. A simple PVC frame could be used to do that, provided that only smaller magnets were used.
How far can you cause deflection of a compass with your large is something I wonder?
Awesome channel!

Thanks!
I started with 2 cube magnets. 1".. Very fun. I wear leather gloves for safety
Most helpful - thank you!
Despite owning a beast magnet and a massive electromagnet I like magnets of all breeds, shapes and sizes. Even the wee ones, but lots of them
There's also first4magnets.com in the UK, they've got many kinds of magnets including the high-grade N52 ones. They don't have huge magnets, but their largest can lift 150kg, enough to mush your hands.
I got my first one from there, it was a small disc magnet that could hold around 27 kg. Good little starter magnet.
Brilliant video. I am enlightened.! Thank you
This video is very useful
If you want to see what a magnetic field looks like in a ferrocell just click my icon. Hardly any body knows what a ferrocell is. simply it is 2 pieces of glass with ferrofluid between them and lit with LED lights. A magnet is placed close to the glass and a visual of the magnet field is seen. Its 3d too but you cant really see that in a video.
nice video and info bro keep it up
I would love to buy one of these for rosie o'donnell for xmas.
Please make a video on the macho set
Great glad I watched this first thanks!
Make a video on the Macho set!
Thanks man good stuff.
I would like to see that video about the 'macho set' :P
I recently upgraded to a 2" x 2" x 1" magnet after having two 3/4" diameter x 1" magnets for a long time, inspired by your videos :) Do you have any suggestions for what I might get next if I eventually get another one? (Or something particularly interesting to do with that size?) Really appreciate your videos!
Benrob55 Thanks :) Personally I would go for a 2" cube. The extra thickness makes it a very powerful magnet. But only buy such a monster if you have handled the 2x2x1 without any incidents ;)
What kind do you now have?
@@karenmmcthree I have a 2x2x1” block and a 2” diameter x 1” disc. I didn’t end up getting a 2” cube (yet...). And I keep the block and the disc on opposite sides of the room haha.
@@Benrob55 where did you get it? Thank you
@@karenmmcthree I got them on Amazon.
Do a review on the big magnets please
Very informative video. Thanks.
You can get big ferrite magnet in speakers
Thank you for the video 🙌🏼💯
