How Magnet is Made

How Magnet is Made

Magnets are all around us. You’d be surprised to know that all known materials exert some sort of magnetic force but it is so small that it is not readily noticeable. With other materials, it is much larger and these are referred to as magnets. Magnets aren’t just used to stick stuff on the fridge. They can be used to power MRIs and generate electricity among other things. But how many types of magnets are there and how are they made?

Worked at a place that made neodymium magnets. They melt the iron then add the boron and neodymium plus a little nickel and cobalt. Then it is cast and crushed to fine powder under nitrogen. This powder is pressed into blanks that are sintered under a vacuum with a rather weak magnetic field on it, This weak field does not charge the magnet but polarized the crystal structure so it can accept a charge. Next they are cut and ground to spec and coated with epoxy or plated with nickel. When they are ready they are charged by a powerful pulsed electromagnet. It has a field a couple orders of magnatude stronger than the resulting magnet. It will wipe your credit cards from 12 feet away.😮

One of mankinds greatest failings has been to not see the full potential of what can be done with magnets. Typically, we just thought there was nothing left to be discovered about magnetism, so we didnt try. Same with crystallization, photosynthesis, ion collection and storage, chromosome manipulation.

I purchased a sample pack of rare-earth magnets from AMF in Australia about 6 years ago for $25. My only online purchase ever. Those cute little magnets have transformed my workshop. Tool holding and so many projects, I'm amazed there are still a few "wasted" holding photos on the fridge. I should proabably order some more. $0.02

I'm intrigued why this manufacturing process isn't fully automated

👍...Incredible process....makes me really appreciate the magic and fun magnets provide.

Dont get amazed, ancient egyptians didnt have neodemium magnets, not also liquid oxygen, the stones were molded, molten sand

jesus, its like you kinda researched this stuff and threw together buzzy words to make it sound legit.

Nice, but why the AC DC V screens are inverted in the video ?

[smithno]

How come some of the images are reversed?

6:20 look what the magnetic fields did to his hair.

Why are the images of meters backwards?

[violiniztapianizta]

you should have at least, gave citation to your source. How its made.

7:58 do you mean "pattern"? Not "Patton"?

[ericschmuecker]

Did you slow the voice down? It's not worth making the video longer.

There are so many videos on YouTube detailing this process. They all use this exact footage and very similar wording. They cover the same points in the same order. Even the list of ingredients is the exact same in order and wording. And no sources cited. What kind of mass plagiarism is happening with this specific topic?

[teresashinkansen]

This is the same as the "How its Made" video about magnets just with some extra footage. This is borderline plagiarism. At least try using an original script instead of just altering a bit the original.

hello there, for me this is an interesting issue, something that needs to be explained in orders, step by step...Here, i feel like someone is reading a story, a report, .. and at the end, ..not many can remember anything good, ..I am sorry, but, that's my opinion. Thanks, anyway!
