The armature is made to revolve rapidly between the poles of the field-magnet by means of a handle that works up and down.
In this case H would represent the armature and E the field-magnet.
The magnet, called the field-magnet, is merely to furnish lines of magnetic force.
The coils E are included in the circuit of a generator F, by means of which the field-magnet is energized.The inventions, researches and writings of Nikola Tesla
