Question: What makes a magnet magnetic?

Megan Maunder answered on 17 Mar 2020:

Everything is made up of tiny units called atoms. Each atom has electrons that spin around its core, called a nucleus Electrons carry charge and their movement an electric current and causes each electron to act like a microscopic magnet.
Something which has electrons that spins in opposite directions won’t have magnetism but if most electrons spin in the same direction the substance becomes magnetic.
All magnets have north and south poles, like poles repel and opposite poles attract.
