Model AC DC Generator
Generates both AC and DC. When the two brushes of the generator are put in the two ends (on the complete loop) of the commutator, the output is an AC. When the brushes are put in the middle (on the half loop) of the commutator, the output is a DC with one spare belt Includes Instructions.

Induction Coil, Ruhmkorff
Supertek induction coil is a device, which produces a spark with an input of 6 to 12 V DC and is therefore ideal for use with vacuum tubes, eudiometers etc. A fully adjustable vibrator system is incorporated and spark suppression capacitors are housed in the base. A pair of pointer electrodes is supplied with the instrument. Pointer electrodes have an insulating handle for adjustment of the spark gap. Low voltage input is given via a pair of mounted 4 mm Sockets. Induction Coil.

Induction Coil
This box-form Induction Coil has a 50 mm spark gap and can produce pulses of high voltage spark from a low voltage direct current source such as a battery. It is suitable for use with gas-filled discharge tubes, vacuum tubes, eudiometers and for general laboratory work. It is comprised of two coils fully enclosed in a polished wooden case with binding posts. Spark gap at the discharge points can be adjusted by sliding rods back and forth.

Primary and Secondary Coil
The apparatus demonstrates the principle of Electromagnetic Induction and helps explain the concept of a transformer. Primary and Secondary coil consist of coils mounted on plastic spools, with 2 binding posts on each coil. You can slide the primary coil inside the secondary coil. Also includes a soft iron core for induction experiments. Primary coil has 480 turns while secondary coil has 3800 turns. Requires a galvanometer and bar magnets, not supplied with apparatus.

Air Core Solenoid
Air Core Solenoid helps investigate the magnetic field of a long coil. It can also used with the Current Balance as an accessory to measure the force on a conductor in a magnetic field. The solenoid has coils wound on a plastic tube with approximately 575 turns of copper wire. It can carry a current of 5A continuously, or 10A intermittently.
