Electromagnetic flashlight with clear barrel demonstrates how a moving magnetic field creates current!

Look inside the clear case as you shake, and see the powerful magnet pass back and forth through a loop of wire. Electrical energy is stored in a capacitor that can be charged hundreds of thousands of times. The bulb is an ultra-bright white LED. 30 seconds of shaking provides a full charge, and will produce a beam of light for several minutes. Use this to demonstrate many concepts on electricity and magnetism!
