Using the "Electricity & Magnetism Light Bulb Demo", you will demonstrate to your students the relationship between electricity and magnetism in an amazing and unconventional way, using a light bulb under conditions not normally observed in everyday life.

Compact, all-in-one apparatus in light-tight enclosure to study the motion of electrons under the influence of electric and magnetic fields and determine their charge-to-mass ratio.

Measure the charge/mass ratio of the electron!

The classic St. Louis Motor gives students a great introduction to electric motors. Now, modern high strength magnets, precision engineering, and industrial brush technology have brought this traditional apparatus up to date.

This DIY speaker kit is all you need to construct 10 loudspeakers so that students can get real, hands-on experience of how the device works. 

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.
