Demonstration Electric Motor
Code: PHMC0281
A model of the simplest form of D.C. electric motor, having 2-pole armature wound with enamelled copper wire, and a permanent magnetic field provided by a removable bar magnet. A disc-type commutator is incorporated and external connection to the phosphor-bronze bushes is by means of a pair of 4 mm. sockets. The motor will operates on 6-8 Volts D.C.
Demonstration Dynamo
Code: PHMC0284
This model uses the same basic assembly as the motor, but is mounted on a baseplate 230 x 90 mm. approx. which also carries a hand-drive pulley 120mm. diameter coupled to the smaller dynamo pulley by a rubber belt to give a step-up ration. Electrical output is via a pair of 4mm. sockets. The model may also be used as a motor on a 6-8 V D.C. supply.
Millikan's Oil Drop Apparatus
Code: PHMC0287
Determination of charge on a electron by measuring a known distance on the basis of number of times of fall under gravity, and of rise in uniform vertical electrostatic field in a series of charged oil drops.
