Seems unreliable. Usually part of why this high end equipment is so expensive is because of the incredible robust build both physically and firmware wise as well as the extensive testing that goes into it. Slapping something like android which is a mess of a system based on a million patches that nobody really knows when it works and when it doesn't. I dunnoooooooooo
@@bjordsvennson2726 Well I do work in mobile app development with both android and ios. And know a bit about the history of android and how it came to be. Not to mention I've had nothing but android phones for the last 9 years. Is anyone looking for "cheaper" as a selling point in their high end equipment? Lastly, I think It would be beneficial if you're trying to make a high performance racing car in the present day, you should design the wheels from the ground up, not start with a set of 1925 Buick wheels and patch them as you go.
Have you considered mounting an RGB led on the probe and connect that to your meter so it would change colour according to the measurements? Then you can take a long exposure in the dark while waving the probe around to create a visual map of the field (light painting). Of course you need to be careful so that the current flowing through the wires and led doesn't affect your measurements.
Now, that's thinking out of the box :) Great idea, but I will not be doing it with this precision instrument. The probe alone is worth around $1600... Thanks for watching!
It makes sense to me if I think of it like hooking up batteries either in series or parallel. One way will increase your voltage while the other increases capacity. Seems to me pretty similar to your monster magnet tests. Your double magnet configuration seems to have more pull on the poles because it's 2 magnets instead of 1 and your 1 magnet configuration had more draw on the midline on the side because it was just a single massive magnet. It didn't have the seam that the 2 magnets had and was stronger for it.
You're not joking about those magnets not being toys. I get nervous just watching you handle them! I know you are very careful, but, PLEASE BE CAREFUL! Love your channel, BTW.
Thanks. The first 4 years in my TH-cam career I made 0 cents :) The partner program wasn't available in Denmark until February 2013, so yes - this is primarily for the passion of video making and knowledge sharing :)
Yes, all the things I have to take into consideration with my large therapy magnets. I like to keep them in place with a steal washer but the washer will always go to the edge and if possible on the edge between the negative and positive. Which brings us back to the magnetic field preference for the material it travels through. When I tested the field strength in front of my body with the magnet on my back it is stronger thatn at the same distance through the air.
attracting forces in a magnetic field are caused by gradients in the magnetic flux, not the flux itself. A very strong but perfectly homogeneous magnetic field would only turn around ferromagnetic objects, not attract them. This is why compass needles don't experience a net force towards any pole. This is also why the attracting forces are largest close to the edges of magnets, where the field changes most strongly with distance, i.e., the field gradient is large compared to the center.
Have you ever considered hooking the probe up to a 3 axis CNC machine and recording the data from all three axes of the probe and the CNC position data? That way you could map the actual vector field in 3-Space around the magnet. If you want, I could probably write some mathematica code to render the field from the data if you ever get around to it.
I was thinking the same thing. One caveat is that the motors and metals on the robot arm will throw off the readings a little, so you'll still need a few manual measurements for confirmation.
Wow that was awesome thank you so much for making this it is going to be a very interesting conversation with my friends about this video thank you for all the hard work that you are doing keep up the great work you have no idea how much your videos are useful and the way you deliver the information is amazing I hope I'll be able to meet you one day you truly inspire me to keep learning new things thank you And as always : greetings from Iran ❤️🌷
Because water is a diamagnetic fluid does that mean it would be possible to create a vortex in a glass of water without the actual magnet being in contact with the water itself?
You have to remember, that like all dipole fields, magnetic field strength decreases with the inverse CUBE of the distance. So even if they are very strong from very close, you don't have to go very far away for the field to drop off prohibitively and then to undetectably low levels. It's because there's a south pole and a north pole together, as there are no magnetic monopoles. You would see the same thing if you had a large positive charge right next to a large negative charge, rather than a single charge of one sign, it falls off with the inverse cube and not the inverse square because the 2 opposite sign sources cancel each other out more completely the futher away you get from them. It's also the same with tidal forces in gravity, the dipole there is the 2 sides of the object experiencing the tidal forces, which relative to each other are a plus and a minus.
Have you ever just thrown a large cloud of iron powder into all the air surrounding a large magnet? Film it with a high speed camera. Is it possible to get oppositely charged very fine particulates/powder to try? I'm interested in if it's possible to get a visual 3d view of the field? Or has this been done?
What is it that turns out, if you throw an iron loop on a magnet, then the field will spread further? Cool! Although I thought for such magnets the field strength is about one and a half Tesla, and here there is quite a bit.
I think it would be really cool to somehow get the magnet close to a cnc machine and make a 3d map of the magnetic field. It would make for some really cool visuals. Where are you going to find a cnc machine that can accomodate this thing without flipping out though? lol
I wish you were my neighbor ! We would have a ball ! I think you enjoy studying magnets as much as myself. My lifelong obsession with them started when I was around 5 years old. I'm 57 now. In 2014 I wrote a scientific paper on what I would like to create, it's called, On the theory of semi degenerate matter magnets and their properties . I was honored to hand it to Dr Michio Akaku in person. It will take some time for the technology to make it possible, But , You , Will reeaalllyy like these magnets , if we can do it. Thank You, Great channel and work you do.
It would be great to compare this with different electromagnets. And measure the field strength in the air gaps especially with an electromagnet with an almost closed core! :)
Quick tip you shouldn't yse grid lines for graphs as they make it difficult to see the trend. Optical illusions can make them look wavey even though they are not.
What i wonder is how is the shipping and storage of such magnets done. Like, you can't simply put them in the mail and send it right? But i don't know, would you need a truck that isn't made of metal? i don't think such thing even exists.... And about storing them in your house, how much meters apart you keep them from each other? and don't they mess with other electronics? And do you put them in some protective box? Magnets are amazing, like your videos :)
Imagine just one day you are sitting infront of your coffee table with your high power industrial magnet sitting next to it, and then suddenly it flies past your head and through your wall into the kitchen where your other high powered industrial magnet is.
I'd imagine magnetic fields behave similar to gravity as far how the effect spans infinitely, just getting exponentially weaker the further you go. That sure is one sensitive probe though.
No wonder the warning at the beginning is there, I recently salvaged some extremely thin magnets from a hard drive and the magnets pinched me enough to make by finger start bleeding from the pressure. Imagine what these ones would do.
Interesting video! I always wonder what these fundamental forces are betraying about the existences which govern them. Is there a higher-dimensional shape or truth whose characteristics are reflected here? Are we too short-sighted to see them? Electro-magnetism seems so odd... But still beautiful! Please keep up the videos!
Hello, Have you ever broke any of your magnets? I am interested because I have and from what I see on TH-cam many others have also. I hope you post many more videos! This one was great!
It is the teslameter's electronics box that needs to be at max 150 G. I wanted to see how close I can have the box while measuring on these giant magnets. The teslameter's probe will be fine in magnetic fields as high as 35 T / 350000 G. Thanks for watching!
. Perhaps you missed the most important experience, this interaction of a needle with a magnet. Put the needle on a string and move it over the magnet - you will be stunned! . Вы упустили пожалуй самый важный опыт, это взаимодействие иглы с магнитом. Подвесте иглу на нитке и поводите ею над магнитом - вы будете ошарашены!
So if you were to go out to an empty field what would your tesla meter read. How much of that change was due the the interference of other sources closer and by altering their field you altered your readings? I know electricity puts out magnetic fields but not sure if your meter would pick those up and still not positive on the effect of a slow moving magnetic field effects on the emf field from electricity.
Now I know why all my compasses seem to point towards your house.
Remember that air is not the best magnetic conductor so a person living on the opposite side of the globe...

Why did it take TH-cam a week to let me know you uploaded? Ridiculous. Ridiculously good video.
Outstanding alliteration
Where can I buy the this magnet
it was cool to watch the meter speed up inversely via the sq of the distance as you got closer.
Its actually an inverse cube relation, due to dipole forces cancelling out.
The monster magnet is back
Volume 150 mm =1,767 mm3 vs 200mm = 1,570 mm3 ==> 150 mm raw materials are expensive high price

I wonder if those magnets could be strong enough to pull a nail out of wood. Like the nails in the floor holding the house together under your carpet.
Probably not. If you had nailed down a piece of steel, maybe. But there is just not enough material to pull on. It would be interesting to see him try
Your right!
You should put the magnet under a transparent board and dump some iron dust onto it. It would be interesting to see how big the lines would get.
This video is why I’m amazed a compass works in your house lol
Always interesting and educational! Thanks!!
That metal ball going toward the edge of the large magnet shows its power. There is only a single frame where you can see it moving
I do really enjoy your videos //Jeg er dansker

I'd imagine magnetic fields behave similar to gravity as far how the effect spans infinitely, just getting exponentially weaker the further you go. That sure is one sensitive probe though.
Although a dipole magnetic field decays at an inverse cube rate, whereas gravity decays at an inverse square rate.
Gravity is incoherent magnetism.

It would have been better to plot the magnetic field on a log/log graph to show the 1/r3 relationship.
Is this particular model of magnet actually used for anything besides cool Braniac videos?
Good question. It does seem impractical to have a permanent magnet so powerful anywhere
holy maceroni. 2 stacked subs. that monsters move a lot of air
