A cutaway copper pipe with a magnet drifting slowly down inside, wrapped in glowing orange eddy-current loops

Why Does a Magnet Fall Slowly Through a Copper ...

Copper isn’t magnetic, yet a strong magnet dropped down a copper pipe falls in slow motion. The reason is Lenz’s law: the currents the moving magnet induces always push back...

Two hundred years ago electricity and magnetism looked like separate curiosities. Then a compass needle twitched, and within fifty years they had become a single theory that also explained light.
