I pulled this powerful ceramic magnet out of a microwave magnetron.
While I was prizing it out, it chipped a little and I now have this sliver of a magnet.
When I try to put it back into the hole whence it came, it gets violently repulsed by the main magnet, and I have to turn it backwards to be able to touch the two together. How come? shouldnt it be attracted to the magnet it came from?

>Asking how magnets work
you're just asking to be memed
but then again maybe that's what you wanted all along
PS: what can I do with a cool ring magnet like this?
You could make a magnetron with it

Magnets and Monetary systems. 2 things the pleb must never understand.
What direction is it magnetized along?

So how do magnets even hold themselves together? Why don't we have an exploding magnet crisis? Why doesn't running a current through metal cause a violent explosion?
>>7979688
Because metallic bonds are stronger.
>>7979688
The magnetic repulsion is way weaker than the molecular bonds holding it together..

Congratulations OP you have developed a new form of rocket engine using solid magnets with laminated layers that just fragment off providing thrust - how cool is that !

This is totally impractical, but it actually would work, wouldn't it? Rocket science is easy senpai

The main magnet has more gravity inside it, and the excess gravity is gravitationally repulsive in the same way dark matter is, so it requires work to put back together
This is all explained in any decent relativity class
