Induction Accessories Set   (EE - 566)

Comprises a six turn copper coil to show the production of a heavy current at low voltage by the melting of a nail, a solder trough to demonstrate the principle of the induction furnace and a set of aluminium rings to show 'Thomson's ring effect. Two rings are 'solid', the third split to show that the rings must be continuous for levitation' to take place.

Motor Accessories Kit   (EE - 567)

For demonstrating the effects of eddy current, and the principles of the shaded pole motor. Comprising a pair of quadrant shaped eddy current plates, one plain, one slotted and an aluminium motor disc with a pole shading piece. A vertical support rod fits into the hole provided in one of the transformer pole pieces, and itself carries two transverse holes with clamping screws to accommodate the spindles of the quadrants and motor disk respectively.

Dissectable Transformer   (EE - 568)

Designed primarily for demonstration of basic principals of the A.C. transformer. The coils and cores will also serve as the basis of many experiments in electromagnetism using either direct or alternating currents. Supplied with 1 Clamp base, 1 Laminated 'U' core, 1 Laminated armature, 2 Soft iron pole pieces, 1 Coil of 300 turns 4 amp., 2 Coils of 600 turns 2 amp., 1 Coil of 1200 turns 1 amp., 1 Coil of 3600 turns 0.3 amp, 1 Coil of 12000 turns 0.05 amp. All coils are enamelled copper wire wound round on high impact plastic moulded bobbins. The base is provided with tommy -bar screw to hold 'U' core.

It consists of following components:
a) Alloy stand with detachable clamping arms.
b) U & I laminated cores of cross section 32 x 25mm.
c) E & I laminated cores of cross section 32 x 25mm.
d) Six coils, with 4mm socket terminals wound on plastic
bobbins
e) A pair of pole pieces.

Note: Coils of different values and turns are also available.

Orested's Apparatus   (EE - 569)

To explain the effect of flow of current in conductor on the magnetic needle. Consist of a rectangular section of copper wire of dia. 6mm, mounted on an insulating base over a post on the axis of which a 75mm magnetic needle is mounted. When current flows in the conductor, needles moves around depending on the direction of flow of current.

Ampere's Rule Apparatus   (EE - 570)

Study the magnetic field around a wire. Consists of a heavy copper wire arranged so that iron fillings can show the direction of the field around the vertical portion of the wire. A compass can be placed under the horizontal portion of the wire for showing the same effect. By sending current through the wire and noting the directions in which the needle points, one can trace the lines of force around the wire and also determine the direction of the current.

Ampere's Rule Apparatus   (EE - 571)

Same as above, wooden, economy model

Induced Current Apparatus   (EE - 572)

Used for the study of induced currents, comprises of two solenoids with one smaller of dia to fit in the bigger one.
