Same I thought they took people to a village in Africa to burn them alive in order to extract the metals from their blood in which they pour into magnet molds. This video seemed to disprove my predictions. How extraordinary!
I can't believe that when it comes to manufacturing magnets, one of the steps to getting magnets out of their molds is to beat the living crap out of it.
For those of you thinking that this process is wasteful and sloppy, let me introduce you to the metal industry, where a lot of processes like this are the norm. Mass-produced designs for items like these are very hard to make safely in any kind of laboratory or workshop, and factories rarely involve some kind of quiet, safe environment. Metalworking in general is very loud, messy, and slightly dangerous. That doesn't mean that a lot of the materials go to waste, though; the sand, concrete, and metal scraps used are usually ground down, cleaned, and recycled for later use again, since its mostly just silicates and metals. The metals are even sometimes chemically sifted back into their base components and reused as well, since they're the same metals that will go into the magnets anyway. This is coming from a guy who worked as a metalworker/welder for a few years, and who has absolutely set himself on fire several times from just being around red-hot metal for too long. It's just the way it is.
@Sebastian Thor Nope, that's just the way the industry is in general. Some countries have worse practices, but it's mostly the same. When you're dealing with handeling molten metal, there's not much else you can do
Never thought that making magnets is so labour intensive and difficult. Really expected the process to be almost fully automated. Thanks for the video!
Metallurgy may be more automated in developed countries, but since the huge majority of it is done in poorest countries, it does end up being more labour intensive.
This looks like a shop that makes low volume custom shapes. These are also cheap nickel-iron based magnets. They are still used in cheap dc motors and similar products, but high efficiency and industrial products almost all use neodymium-iron-boron magnets, which are much stronger, and made via sintering, to tune their properties more precisely. Those are generally made in massive batches. And the processes are much more automated.
A certain part of my modern brain understands the physics behind magnetism, but the rest of my brain refuses to completely believe that it isn't just magic.
Or, could it be that this is yet another example, that shows how all the fundamental pieces of this reality were designed to function as a symphony of predictable results.
It’s 2am. I’m lying here in my bed trying to get to sleep and the stupid thought of how tf magnets are made is literally keeping my up. I was so worked up I got my phone and searched up this video. Needless to say I’ve finished with more questions than I started with and now I really cannot get to sleep.
@@j.k.4479 The way I heard it, they were discovered first; a Greek sheperd named Magnus was herding his sheep when his metal staff got mysteriously stuck to some hematite rocks on the hillside. At least, so I've heard
Weaker magnets will do the work just fine..there are naturally formed magnets, but it's very weak.....guess that's how they made the first magnet....by using the natural magnet......
Informative to say the least. As a kid, I had a set of Brio trains that depended on magnets to link them together. What was interesting however, was the fact that if you did a 180 (Half circle) on any of the train cars, and the polarity was the same, they repelled each other instead of attracting. As a 'youngin', I was mindblown by the concept and would always try to force them to link. Obviously, no such luck :P
I've always thought how magnets would be made but for some reason i didn't searched it till now and now that ive seen it, it has matched my expectations of "there must be some hardwork to make these things"
A very hard subject to figure out tbh, just try figuring out how they made magnets before they had generators to make electricity, how did they make electricty? i've been so confused by this
This was my life question, how they r made, finally I found the answer after 40 years, thanks a lot for delivering this wonderful answer for myself question. Keep it up. Regards Prudvi Raj
Dakota LaBarr this video is 7 years old. Maybe even older. It’s just a repost. What I want to know, is why isn’t there any really recent informative video on how magnets are created? Is it because they can be used as weapons or something?
@ジャック- jack bro either I didn’t pay attention or we ain’t from the same planet trust me if I was taught how to make a magnet I wouldn’t for get it I’d have destroyed so many batteries
First, I can't fathom how anyone put this process together. Second, that dude should be wearing some kind of respirator if he is filling that silica sand all day. His lungs are in serious trouble.
I seriously thought they'd get the magnetic ability immediately after getting molded together and all the metallic objects nearby would stick to it hence they were made in an anti magnetic chamber or something. But it looks like they need a kick to get started..it's good in a way tho
@@andyhiett2734 Rare earth magnets aren't just found in the ground, first they're ores that get smelted and then manufactured into magnets just like this.
This is a very old way to do it. Now there is a much easier way to make magnets. Plus there are now neodymium magnets which are much more stronger than these.
