A copper wire wound on a iron rod is called as iron cored inductor. Basically iron cored inductor having two components resistance and inductance. These two parameters depend up on the permeability of the core. In this paper variation of induced elecctro motive force (EMF) in the secondary coil placed on the same core at different magnetic fields are presented. A detailed study of dependence of resistance and inductance is also presented in this paper.

This paper proposes the dependence of open circuit parameters of two mutually coupled coils wound on a nickel solenoid core at different temperatures. This paper helps in designing range of optimum temperatures of nickel core to get better induced EMF and reduced No-Load losses. The behavior of magnetization component with temperature is also presented in this paper. The components R0 and X0 variation with temperature is plotted for different voltages under core temperature variation. All these results are examined experimentally.
