I've had neodynium magnets attract each other fiercely enough to fragment upon collision. Truly an impressive material.

[@terrandroid]

They break really fast, not very strong

[@mr702s]

It's not as impressive when you learn about how structurely weak those magnets are. It feels strong when holding but it's not.

[@rokibeeskiroodroki9018]

Yes, consumer grade neodymium magnets should be in a harder shell than just that thin and cowardly metal skin they have by default.

[@MFKR696]

@@terrandroid It has nothing to do with their strength. They are strong, but they are also brittle, which is why they shatter. Over-hardened, non-tempered steel does the same thing. It breaks like glass.

[@onradioactivewaves]

The cintered magnets use a formula (ratio of elements) that can hold a stronger field, theres other types that are not as strong magnetically but are stronger physically by having a true metallic crystal structure, for applications where the magnet needs to not break. Its a tradeoff between the required physical strength versus magnetic strength.

I knew that rare earth elements can be hard to separate, but I naïvely thought that the neodymium in NdFeB magnets would be nearly pure. I’d guessed that it had to be or the magnet would be weak. Very interesting to know!

[@off6848]

But isn’t it still relatively pure? I think that just by working in a specific atmosphere and burning chemicals down you could be introducing additives on the spot

[@chumbomcwumbo9640]

Many people have the misconception that America's technological lead during the cold war was because of basic science. This is not true at all. Most of the hardcore scientists making waves in America were European imports. America excelled more in industry. In fact, the Soviet Union had extremely advanced basic science. Their chemists and physicists were probably actually better. Even today, any American college research library worth its salt will have a few dozen shelves worth of old Soviet chemistry journals. The failures of the Soviet system were not scientific at all. Communism just doesn't work!

"After a couple of blows from a hammer such magnet easily breaks into pieces" :-D I'd give an extra thumbs up for the comedy value of that to be honest.

[@hankclingingsmith8707]

Stupid

[@DieAnderTier]

Try “beating the shit” out of a cm thick slug of copper, stainless, brass, MOST metals won’t shatter like that, what are you on about?? He was doing it on wood so it appeared more bouncy but these magnets are so brittle that they regularly break when just snapping together.

[@xxxggthyf]

@@DieAnderTier That depends entirely on their crystalline structure and that depends on how they have been treated. A heat abused brass casting will shatter if you look at it funny... Same goes for aluminium and pretty much every other metal. In any event you are missing the point. Saying something easily breaks when you hit it with a lump hammer isn't much of a demonstration of how brittle it is. It's a bit like saying the human thumb is very delicate because it easily breaks if you hit it with a lump hammer (Trust me on this one... I have fully scienced it)...

[@DieAnderTier]

@@xxxggthyf Fair I guess. I just hate how easily those little bucky balls break. Hard drive magnets are cheap and plentiful so it doesn't matter if they chip but balls are "supposed" to be round. Lol I haven't tried that experiment myself but I did try the variation where the metal saw slips out of the groove near your thumb.... Hopefully that's enough data, we don't need to repeat these!

[@xxxggthyf]

@@DieAnderTier Well quite. Sometimes one experiment is all the sciencing we need to establish the validity of our hypothesis :-D

The other rare earths could strengthen or weaken the magnet. I would not be surprised to find them.

If you do a test for radioactivity, the sensor detects the presence of nuclear radioactivity in the magnets. It's worth trying to check this out.

Love the way he says HOWEVER❤️

[@SeanBZA]

Yes, the coating is important, otherwise you end up with a pile of fine magnetic powder where you once had a magnet. However I find it differs from magnet manufacturer and batch to batch just how fast they disintegrate.

[@off6848]

What happens when you change coatings? Tin? Gold? Copper

[@SeanBZA]

@@off6848 Does not really matter the coat, so long as it is not going to react with the inside material and is reasonably inert. Most common is to have a thin flash coat of copper and then a thick coat of nickel applied as a seamless electrolytic coat, so that the inner material is kept oxygen free. Gold would work well except the copper plate and nickel would have to be applied as well, to keep the acid bath used to dissolve the gold from dissolving the magnet as well, plus the material would be changed chemically. however some are gold flashed to provide extra protection, though most is the nickel barrier.

FYI, the process of melting together loose particles of a compound under pressure and surrounded by inert shielding-gasses is called Sintering.
