A Highly Sensitive Electroscope

Convenient and Easy to Use

Magnetic wand, Use this wand with our magnetic marbles or other magnetized items or pick up those paper clips you just dropped. It has many uses and is fun to watch in action.

Demonstrate the transfer of mechanical energy into electrical energy with a simple motion of your hand.

The Eddy Current Experiment demonstrates Lenz's Law.

Graphically illustrate the fact that like charges repel each other.
The multi-colored ribbons are connected to a suction cup that sits on top of a Van de Graaff generator. As the generator operates, the ribbons accumulate a charge and stand on end.

Demonstrate magnetic fields on your desk or overhead with this clear container of iron fillings. Using magnets, you can show students how the fillings move and cluster together.

Quality Lamp Receptacle.

For your Electrostatic Needs!

This generator can perform all electrostatic experiments on a spectacular scale.

A bare copper wire of the highest quality. Available in several standard AWG sizes.

A high quality enameled, copper magnet wire.

A good quality bare iron wire. AWG 20.

Use these flexible magnetic strips for experiments, to hold objects in place, or for creating your own inventions.

Complete electricity kit in a convenient storage case.

Nine level conductivity meter shows the relative conductivity/resistance of liquids and solids. As the conductivity of the tested material increases, the number of glowing red LEDs will increase to a maximum of 8, which indicates a very good conductor. There will be zero glowing red LEDs if the material has a very low electrical conductivity (is a good insulator).
