"Wards"

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.

The Demonstration Transformer Kit is a safe and convenient system for AC and DC experiments up to 0.5 amps.

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.

This pulley is ideal for use with photogates sensors. Pulley is mounted on free-running ball bearings with minimum friction. Mounted on a removeable rod of 150 x 10 mm diameter.
Diameter 65 mm with spokes
Ideal for use with Photogates

Mounted on a wooden stand with a scale, the apparatus is comprised of a three-limbed glass tube with rubber tubing on the center.

Demonstrate the effect of pressure to water depth.

Mounted on molded plastic base, the unit consists of a base into the top of which may be screwed one of a set of four vases of differing shapes. An aperture in the bottom has a thin rubber diaphragm across it, bearing upon the short arm of the lever pointer. A moveable index on the vertical rod enables the height of water in vases to be set at same level. The apparatus is mounted on moulded plastic base that measures 25 x 17.5cm. The experiment is performed by screwing in each vase, in turn, and filling with water to the same level. It will be seen that the given height of water will result in the same deflection of pointer whatever shape of the vase.

Show the difference between three pendulums with different lengths.

No need for a mirror support stand with these mirrors. Silvered back mirror with a protective coating. Mounted on wooden block 20mm thick.

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