Comprising iron U-shaped core of circular section, with armature and carrying hook.
Wounded with insulated copper wire and provided with connectors for use on 4-6 volts D.C.
A former with terminals and engraved circle marked 0 – 180° – 0 figured every 45°, wound with 30 turns of insulated copper wire, complete with a magnetic needle 75 mm long and a pivot for the needle.
This demonstrates the action of electric current on a magnet.
A cobalt steel needle with agate bearing supported by pivot is mounted on a plastic base and surrounded by rectangular frame fitted with terminals.

This apparatus demonstrates the magnetic field patterns associated with the different shapes of current carrying conductors.
Comprises three conductors, each of different shape/configuration – straight rectangular, circular loop and solenoid all mounted on a plastic base.
Each configuration is provided with a pair of 4 mm sockets to connect them to a low voltage DC power source, with output current not exceeding 5A With the included iron filings and 8 magnetic compasses, you can investigate the associated field and flux patterns.
For demonstrating that some metals are magnetic whilst others are not and for general ‘Metal Identification’ exercises.
Comprises sixteen discs, 25 mm.
diameter 2 each of Mild Steel, Stainless Steel, Brass, Zinc, Nickel, Silver, Bronze, Aluminium and copper.
One of each is stamped with the name of metal.
the other is unmarked.
