Force on a conductor balance - It is used to demonstrate that when a current is passed through a conductor in a magnetic field, it is subjected to a force of attraction or repulsion depending upon the direction of current in it. It consists of a plastic base 160 x 140mm on which two contact pillars are mounted. Each pillar is provided with an external circuit. A balance 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 1mm, rider of 1 gm weight.

Induction Coil (Ruhmkorff Coil ) for Physics Lab - The primaries are wound with thicker copper enamelled covered wire on letherite pipe in two layers. The secondary coils are divided into two parts & are given heavy insulation. Each layer is wound in a cover of butter paper & are completing the winding, the entire is dipped into hot wax to seal each layer against moisture effect. The coils are housed in a teakwood base, voltage tested condensers are fitted inside the wooden polished base. Handles to get the spark are fitted on it & make or break points are of silver. One point is adjustable to get any cycle. On/off reversing switch commutator working on 6 to 12 V DC. Size - 10 mm, 25 mm, 50 mm, 75 mm, 100 mm

Demonstration Induction Coils consists of two coils wound on separate bobbins, one having many turns of fine wire & the other with few turns of heavy wire. It demonstrates that induced potentials are produced either by movement of a permanent or electromagnet or by a change of current in one coil, fitted with insulated 4 mm socket terminals & supplied with a soft iron core, outer coil is 12.5 cm long & is of 5 cm diameter.

Apparatus To Show Force On Conductor In Magnetic Field - Comprising a strong U-shaped magnet and a pair of brass rails with 4mm socket terminals. A brass axle with plastic discs is free to roll along the rails and completes the electrical contact between them. When the axle is placed on the rails between the poles of the magnet, and a power supply unit is connected, the axle rolls along the rails, away from the centre of the magnetic field. Apparatus To Show Force On Conductor In Magnetic Field for Magnetism Experiment in Physics Lab.
