3.2 THE INDUCTOR
The physical basis for the two-terminal element, called inductor, has been dealt with in
Chap. 1. We recapitulate briefly.
Moving charges, i.e., current flow, causes a magnetic field to be set up everywhere
in space. When the current is time-varying, the magnetic field too will be time-varying.
Time-varying magnetic field produces an extra electric force on charges everywhere – extra
over whatever other forces that are present. This extra force – induced electric force – is non-
conservative and results in an e.m.f. in the circuit. In the case of a closed loop, this e.m.f is
related to the rate of change of magnetic flux by Faraday’ ...
