ADJUSTABLE BRUSHES MOTOR

Observable components of motor. A variety of demonstrations can be performed on this basic apparatus e.g. Magnetic fields, D.C. Motors,series and shunt fields and generators. There is a two-pole D.C. Armature which can be connected to a mechanical device or to another motor for motor and generator demonstrations. Adjustable brushes for contact with commutators. White plated spring brass clamps, which shows the effects of pole separation, supports the two permanent bar magnets.
