Buyer's Guide: Your first neodymium magnet
ฝัง
- เผยแพร่เมื่อ 18 เม.ย. 2015
- Neodymium magnets are so powerful that you should watch this before buying one. I give guidelines for size, shape, grade and coating. In this way you hopefully will have a good start with a nice beginner magnet.

I have no personal experiences with magnet webshops outside Europe. For US/Canada it seems that www.magnet4less.com has the best selection at very fair prices. I haven't found any sample sets in their webshop though.
Another cheap source for neo magnets are scrapped hard disk drives. It can be tricky to open the drives though and the magnets are specialized. Here's my video about them: • Magnet in HDD | Taming...

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!
MrNoodless Thanks! I believe I'm getting better at the voiceovers...
***** Yes :)
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.
+RMoribayashi it's Dave from EEVblog - just google him...
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!
Luke Paul Thank you very much! Always nice to hear that I am not just wasting my time making these videos :)
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.
Brainiac75 12mm diameter and 3mm thickness nickel coating is good because i trying to get 10 pieces and the asked me about its dimensions so?
+Omar Taman 3 mm is thin for a 12 mm diameter magnet. Expect to break a lot of them if you aren't used to handle neodymium magnets :)
I vote for the vid of the macho thing :D
Stefano
Me too!
Stefano i vote for it too!
Stefano +1
I love the way you warn people. The Ferrari for a first driving test was hilarious.
+Ÿ ^_^ łô
Thank you for watching :)
+Brainiac75 are you German?
BlackSheepTV Nope, I'm Danish.
horrible analogy
@Marvin Connor bot
I came here after immediately pinching my fingers between two small disk magnets that I just purchased. I should have known better, having been already been a subscriber to this channel for a while
Challenge - find me the right magnets from here: goo.gl/RUHVQf to enable me to do this: goo.gl/uTHN9Z
+Declan McGuinness
Hi. In the video description for the linked video 3/8 x 3/8" is stated. That is roughly similar to a 10 x 10 mm cylinder magnet which you should be able to find on eBay.
+brainiac75 Thanks very much.
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.
Hi Brian, we truly love your videos! They are informative and very entertaining.
supermagnete Thanks for watching and commenting :)
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.
Where's the best place to get a big square one?
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! :)
That was a very well made video. You taught me a lot. Thanks for making it.
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.
Excellent guide to these new type of magnets
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.
OMG! That is big
Loved this. Hilarious and practical advice. The Ferrari analogy was pure gold. Keep it up!
Thank you for making this safety and information video.
Awesome! Relevant today as it was when published six years back.
Do the macho set. I would like that :D
Awesome list, Awesome recommendations, Awesome warnings. Nice job and well done!
Please do a video on the macho set pleeeeease
Arvid qqu
your videos are always so informative. Thanks for sharing.
Excellent guide.
yeah true
Great videos. Really well done on all I have watched so far.
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.
The way of expressing and your language is understandable thank you for your service to people's
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)
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 :)
Excellent video... And I'm NOT a beginner! Just a great, well presented introduction. Kudos!
+JohnnyJim J
Thank you very much! Experts are also welcome :)
Thank you! :) your videos are super informative and helpful.
Brilliant video. I am enlightened.! Thank you
Absolutely beautiful, Love your videos.
You probably saved my fingers. Thank you for your video.
Need... macho... set... video! :D
This is a very helpful video I appreciate it!! Very in detail!
Because of you im gonna buy a quality magnet. ty very much.
Hey, really really really useful video for mortals like me!!! Thanks a lot for the info!!!! You rock!!!
You really need to make a video about the Macho set. Very interesting.
Most helpful - thank you!
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.
Thanks for sharing. Neodymium magnets can be fun, but when measured in whole inches they are not toys :)
OMG! 405 pound pull
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.
Very informative video. Thanks.
great video i found it very helpful
Thank you for the video 🙌🏼💯
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?
Great glad I watched this first thanks!
This video is very useful
nice video and info bro keep it up
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.
I've bought a set of 50 N52 disk magnets in the size of 10x3mm, and even they impress me very much!
+Seegal Galguntijak
Yes, N52's are impressive no matter the size.
I use Neodymium magnets in my hover board.
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 :)
Thanks man good stuff.
your soothing voice is helping my crippling depression during the pandmic. thank you!!!
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
I like these magnets I want to get some more I have small ones. They can be really useful!
Macho set! Do a Macho set video! MAKE MORE VIDEOS I LOVE YOUR VOICEOVERS AND SCIENTIFIC INPUT!
I'm allergic to nickel. So I'm glad you went into the detail of what they are coated with, thank you.
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 have a 10x25 mm Disc magnet. I had been working with my agnets over 10 months
thanks for your information
Awesome channel!
+James Cooney
Thanks!
We need the macho set video! Now! I can't stand the cliffhanger D:
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.
How would you then classify the magnets used for recovering items dropped in lakes, rivers and streams, commonly called fishing magnets?
Hi Brian, thanks for this informative piece, I have now got lost in Wikipedia entries on Neodymium and REE !!
I was really looking for a way to remagnetise my aquarium cleaner magnets. I do have some old hard drives that I need to put beyond use. Would the magnet from a hard drive be strong enough to re-magnetise the aquarium magnets? They are a pair of 5 x 3 cm rectangles probably 3mm thick and bonded to plastic holders
I for some reason havnt used tools to separate 25*25 mm disc magnets but i have been fine with them i can easily seperat a 25*25 and 50*10 mm magnet by hand
Am i super strong?
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?
those magnets are no joke, they are so powerful I still have the 12 inch magnets are still stuck together, and I can't get them apart
GUIDELINE 1 SIZE - 1:08
GUIDELINE 2 SHAPE - 2:31
GUIDELINE 3 GRADE - 5:37
GUIDELINE 4 COATING - 5:58
how much do you think a N35
50mm×10mm disc magnet will lift??
17kilos on rated box but maybe wrong
i bought my first neodynium yesterday and it's a 6 inch magnet, very very expensive but so powerful. I use him to tidy my room's metal items
How expensive
Nuts .
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
Where is the best place to buy them? I need some for generator experiments 1 to 2 inch x 1/2 to 3/4 inch.
thank you very well made video
Question: How strong pull in lbs would I need to buy to hold a moving quilt(3/8 inch thick) to my truck(without damaging truck metal)? Making a hail quilt. I have used small neo's on my oil filters for yrs. Thanks
Is it a good idea to wear rubber while using magnets or should I stick to the leather harness?.
Fantastic
There are some weird shape very strong magnets in a hard drive, if you open the case. They are much stronger than fridge magnets, but I doubt they are close to Neodymium or other rare earth metals, but I don't know what are they made of.
Thanks for the advice! I have a rather specific question about magnets:
I'm building some furniture and I want to encase magnets in the wood to ensure certain parts stay closed or don't move unless a person wants to move them. Any ideas on what kind of sizes would be appropriate?
That depends a lot on the design, weight of the objects etc. Magnets are easy to shear apart, but hard to pull directly apart. You need to experiment with it.
good vid. thanks 4 sharing
Lol det var først 2-3 dage efter jeg subscribede til dig at jeg opdaget at du var fra Danmark...
Hello sir, I’m working on a dredge that sucks up and sifts millions of pounds of sand and silt from the ocean floor. I’m curious to see if there are any precious metals and I’m thinking about buying a magnet to run over the aggregate material. What do you recommend?
I need a magnet that can fit under my pant leg unnoticeably and strong enough to move a fork from the underside of a table what should I get
hey I love to watch your vids, I saw in your comment that the kits are for European shipping only and I live in the USA, is there something similar to those kits that will ship to the USA?
+Brainiac75
you said that the gold coating was not an enhancer of magnet strength but it is an excellent conductor.
two questions. (and please don't electrocute yourself experimenting)
1. can you turn a regular magnet into an electromagnet through some simple process?
2. if you apply electricity to a magnet coated in gold, how much electricity would it take before the coating melted off?
3. is there a coating that can be placed on a magnet, that's as conductive as gold, but has a higher melting point?
What’s the relationship between “lifting” strength and “repelling” strength ? If you can lift 20kgs, then in repulsion of 2 could they levitate 20kgs?
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.
Thank you :) Yes, and I still have to import the magnets from another country if I want a decent size...
So, when you get a bunch of garbage (metal shavings and such) on your magnet, is there a way to get it off? If not, is there a proper way to dispose of a contaminated magnet? I would imagine the dustman would get gunned down by one.
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 :)
Nice, we don't have such a store in Denmark. For me it would be funny to visit one :D
Thanks!
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.
Would you reccomend a cylinder magnet? Like a D8 H30 neodymium magnet?
I want to stick a small magnet inside an oil drain plug to catch fine metal particles suspending in motor oil. Is neodymium magnet suitable for this purpose? Tried SmCo magnet but it chips easily
I need a magnet which is.. distance between compass and magnet at least 2 foot... Th compass can detect magnetic interference...which one will help me
I bought an 30 x 10 disc magnet and 10x10x10 square magnet as my first neodymium magnets
good presentation ... thank you !!!!!!!!
No problem. Thanks for watching :D
Just bought a 4" OD x 2" ID x 1/2" thick Round Magnet to strap on my back to hold random work tools. Have I made a mistake?
What do you mean by a "thick Round Magnet". *Laughter*.
wow i like that its so good
so a 1 cubic inch n52 cube is good right. my first is bigger than what the expert said
With Great power comes great responsibility
Beautiful video, beautiful accent.
