Motor module with magnets

This module includes a 1.3 W direct current motor (1.5 V to 4.5 V) on the shaft of which is fixed a disc made of a non-magnetic material supporting and protecting 2 powerful ferrite magnets, N and S.
This setup allows for the closest possible approach of the 'rotating magnet' to the magnetic core placed in a coil and ensures the obtaining of a significant signal on the oscilloscope or multimeter.
Motor mounted on a transparent casing indicating the operating voltages.
