Get Your Science On: Photon of the Opera

Joe shows us how we can make an electric generator with a salad spinner, some magnets and a coil of wire.
What’s Going On?
When a magnet is moved by a coil of wires, you can induce an electric current. This is the principle behind how most of the electricity is produced in the world; it’s just a question of where you get the energy to move the magnets. Every time a magnet passes the coil, a small amount of electricity is created, which makes the LED lights briefly flash on.
