Excerpt from Theoretical and Practical Electrical Engineering, Vol. 2

The discovery of electro-magnetic induction was due to Michael Faraday, in 1831. After finding that a voltage could be induced in a closed circuit by moving a magnet in its vicinity, he followed up this discovery by ascertaining that a current whose strength is changing may induce a secondary voltage in a closed circuit near it. If a coil of wire is placed parallel to another coil, the variation of a current in one will bring about the induction of an e.m.f. in the other. This is called mutual induction. Coils operating upon this principle are employed for medical work, where they are called Faradic coils in honor of Faraday. Coils of larger size are designed to excite X-ray tubes or for the transmission of radio signals, etc. The general appearance of a simple induction coil is shown in Fig. 674, The circuits through the coil are given in Fig. 675. Here current from a battery B is led through the primary winding, P, surrounding an iron core, C, and the circuit, which is completed through some form of interrupter, V, leads to the battery via the switch S'. Surrounding the primary winding is the secondary winding, S. When the circuit is completed the current rises in the primary winding and the magnetic flux through the core accompanies its rise. This induces an e.m.f. in the secondary winding.
