Get Your Science On: Photon of the Opera – submitted by Joanne O’Meara

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.

A demo of this device will be available at the Playground during the STAO 2018 conference with instructions on how to build your own.

Thanks for sharing this ingenious idea Joanne I’m going to build one!
