Chapter Six ELECTROMAGNETIC INDUCTION - NCERT
emf in coil C1. It was this induced emf which caused electric current to flow in coil C1 and through the galvanometer. A plausible explanation for the observations of Experiment 6.3 is as follows: When the tapping key K is pressed, the current in coil C2 (and the resulting magnetic field) rises from zero to a maximum value in a short time.

The property of the loop in which its own magnetic field opposes any change in current is called “self-inductance,” and the emf generated is called the self-induced emf or back emf, which we denote as εL. All current-carrying loops exhibit this property. In
