For the study of the fundamental principals of electric motor and
generators. The motor consists of a two-pole D.C. armature. The brush holder, with two heavy binding post terminals,
may be
rotated for experiments. The permanent bar magnets are supported by spring brass clamps which are
un-adjustable in the
horizontal plane to show the effects of pole separation. Complete with two bar magnets, a
