Electromagnetic flashlight with clear barrel lets students see 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. The electrical energy produced is stored in a capacitor that can be charged hundreds of thousands of times. The bulb is an ultra-bright white LED.
30 minutes of shaking provides 2 hours of light. Use this to wrap up and review many concepts in your unit on electricity and magnetism! Length 7in, includes 1 year warranty.
