Video: Everyone knows you can do some crazy stuff with magnets, but things get really insane when you start playing with electromagnets. When you run an electric current through a coil of wire to create a magnetic field, you can chop soft drink cans in half in epic explosions and send discs flying up in the air that will smash into the ceiling.
Electromagnets even have the ability to shrink a coin. It’s awesome.
With the help of music band Arc Attack, Physics Girl explains how it all works in the video below. A strong current creates such a powerful magnetic field that the soda can immediately sears itself in half with pieces flying away from the electromagnet.
