"Wards"

Electric bell that operated on 4 to 6 Volts DC with detachable cover and metal thread terminals.

Demonstrate Lenz's Law!

Learn how to measure the stiffness of wires.

A simple way to demonstrate parallel and series circuits.

The Lenz's Law Kit investigates how much force an induced magnetic field can create.

Measure an electric current by determining the magnitude and direction of the horizontal component of Earth’s magnetic field. Set the compass needle parallel to the coil, pass an unknown current through, and measure the angle of deflection. Features copper magnet wire, adjustable potentiometer, compass, and non-magnetic stand. Required but not included is one D battery.

Made of brass, interchangeable on pillars, fitted with insulators of ebonite on base. Spheres 5cm diameter, Cylinder 12.5 x 5cm diameter, Cone 10 x 5cm length x diameter.

Multiple value resistances with 4mm sockets

This condenser box provides different values of Electrolytic capacitors, ranging from 1μF to 4.7μF. Built on a 8 x 5" plastic box. All these capacitors are of ± 10% tolerance and are of 63 volts working voltage.

Comprised of a thick plastic base with four rubber feet, along with with an 18cm diameter aluminium plate with an insulating handle.
