A kit of magnets and accessories in a storage tray.
Contents :
1. One Horseshoe magnet, 100 mm, with keepers.Two ceramic bar magnets, 75 mm long.
2. Three ceramic ring magnets, 38 mm diameter
3. Two plotting compasses clear both sides, 19 mm diameter
4. One lodestone specimen.
5. One pack Iron Filing.
6. One each strip of Iron, Aluminium, Zinc and Copper metal.
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.
For investigating the magnetic field associated with a solenoid coil.
Coil size 51 x 92 mm.(diameter x length) approx.,diameter of wire 1.5 mm.
Magnetic field Demo, long solenoid
For ordinary magnets, iron bars, strips etc.
Consists of a 250 mm long solenoid wound with insulated copper wire and mounted on a base, with switch and 4mm terminals.
Operating voltage is 12 V A.C. or D.C. At 6A max.
To demonstrate that when a current is passed through a conductor in a magnetic field, it is subjected to attraction or repulsion depending upon the direction of current in it.
The apparatus consists of a plastic base 160 x 140 mm on which two contact pillars are mounted.
Each pillar is provided with an external circuit.
A balanced beam is supported by the pillars on two bearings which form the fulcrum.
Two screwed masses are provided in the beam system, one moving vertically for the adjustment of sensitivity and the other moving horizontally for the adjustment of the equilibrium position, when no current is flowing.
Scale marked 0 to 75 x 1 mm, rider of 1 gm. weight with instruction manual.
