St. Louis Motor Demonstration
Students can explore how a simple electric motor works by doing a series of investigations. This St. Louis motor can be adjusted so students can study the effect of voltage and position of the brushes on the commutator. This model is capable of AC & DC operation. The motor consists of a two-pole armature. The brush holder, with binding post terminals, can be rotated for experiments. The permanent magnets, supported by clamps, can be adjusted to the desired location. This apparatus requires AC/DC Power Supply and connecting leads (not included).

Electricity
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.

Electricity
Induction Coil, Ruhmkorff
Coils are wound with highly insulated copper wire impregnated with paraffin wax; input 6-8 V dc through two 4 mm socket terminals, with an adjustable trembler system. The spark suppression capacitor is housed in the base. A pair of pointer electrodes with insulated handles for adjustment of the spark gap is provided.

Electricity
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.
