Spare belt for Wimshurst machine. This item has two replacement belts, both of which have a 20" circumference.

These robust and engaging kits are designed as a resource for the teaching of introductory electricity.

The Air-Cooled Laboratory Rheostat is the classic lab solution for controlling voltages and currents.

Ideal electrostatic tool for generating voltages.

Demonstrate the conversion of mechanical energy into electrical energy by generating a static charge.

This complete set of materials makes possible multiple dramatic demonstrations of basic electrostatic principles.

This extra large electroscope is ideal for classroom demonstrations of electrostatic principles. A lightweight metal vane is used as a pointer in the electroscope. This lightweight metal blade deflects when the electroscope plate is charged. A transparent scale is provided to measure the angle of the deflection. Front glass window slides up to allow insertion of ionizing material in chamber.

The concept of electric fields can be difficult to visualize, but the Dry Field Mapping Kit makes it easy.

Observe how charges affect one another and propose an explanation in terms of charge distribution.

Create maps of equipotential lines and the electric fields that exist between two charged surfaces.
