Magneto-electric Generator

A current generator operating by maintaining a potential difference at its terminals, by reactions in a field of force, which field is established by a permanent magnet. The cut, Fig. 230, shows the general principle of construction of a direct current generator. The armature is rotated between the poles of a permanent magnet. Any of the regular types of dynamo armature can be used. From its commutator the current is taken by brushes. IMG:8956969607833025625_362F230.jpg: Fig. 230. MAGNETO-ELECTRIC GENERATOR.

In it a pair of bobbins, wound in series, and both either right-handed or left-handed, are rotated between permanent magnet poles. The current may be taken off by two brushes bearing on two collecting rings on the axis of the bobbins, the ends of the wire being connected thereto. Or if a shocking current is desired, one of the brushes or springs may strike a series of pins forming virtually a broken or interrupted collecting ring. This gives a current for medical purposes.
