All the components fit together to allow for assembly of the arrangements required to demonstrate motor & braking effects on the dissectible transformer. Thus it is used to demonstrate the effects of eddy currents and the principles of the shaded pole motor. It consists of a pair of quadrant shaped eddy current plates (one plane and other slotted) and an aluminium motor disc. The hole given in one of the transformer pole pieces, accommodates a vertical support rod which has two transverse holes with clamping screws for fitting the spindles of motor disc and spindles of the quadrants.
