eli5 Why do magnetics lose magnetism when they are heated up?
In: Physics
Basically a magnet is made my putting hot or even liquid iron into a magnetic field where it solidifies. In that hot/liquid form the iron atoms can align with the magnetic field, so they all face the same direction. After the iron solidifies, the atoms can’t move around anymore to rearrange themselves. They stay, all in the same direction, which makes it a magnet. But if you heat that magnet up again, the atoms can move again, rearrange themselves in all directions and now all you have is a regular piece of iron.
