Answer 3

This is science, but okay.
Anyways, electromagnets are temporary magnets, therefore, they can be turned on/off with a switch. Electromagnets are good for generating electricity, moving metal in scrap yards, providing medical equipment with diagnostic functions, like chavy said. And providing computers with computer functions. Electromagnets are pretty rad and this was all in the lesson so guurrrrl.
