Inductance
is an electric circuit property which depends on the interaction of magnetic
field with electric circuits. This phenomenon is referred to as electromagnetic
induction.

Figure
1 above shows an arrangement to demonstrate Faraday’s electromagnetic induction
discovery. As the conductor in between the magnetic field is moved downwards
through the magnetic field, the galvanometer’s pointer deflects one way from
its initial centre position and as it is moved upwards, the galvanometers
pointer deflects in the opposite direction. And when there is no motion, there
is no galvanometer pointer’s deflection. For the galvanometer pointer to deflect
there must be some current flowing through it. This current flowing through the
galvanometer must have been brought about by an induced voltage in the
conductor. The generation of voltage when an electric conductor cuts across a
magnetic line of force is called electromagnetic induction, and the resulting
voltage is called an induced voltage.
