Draw the constructional diagram of iron core inductor and write the working of it.
Iron core inductors allow high inductance value but are limited in high frequency capacity due to hysteresis and eddy current losses.
Iron core increases the magnetic induction of a coil of wire. Because iron has high permeability, it allows more magnetic lines of flux to concentrate, therefore increasing induction.
Upto a certain point this result in a useful increase in inductance. Beyond that point, inductance decreases.
