121) such a scheme is maintained, and the electricmotor is the result. Ay B^ C,and D represent the spokes ofa solid iron wheel insulated#from its axle. D and C arewound by a coil of insulatedwire, making an electro-mag-net. A and B are also wound,hence ABCD is an electro-magnet with its poles at A… … Fig. 121.
