In coil systems, the induced electromotive force (emf) is influenced by several factors: the number of turns in the coil, the rate of change of magnetic flux, and the permeability of the core material. When these factors are constant, the induced emf remains stable. However, experiments with a Nickel-cored coil have shown that increasing the temperature of the core material can further enhance the induced emf, given a consistent rate of change of flux. This led to the introduction of two parameters: the coefficient of permeability and the coefficient of induced emf [1]. In the present paper, these two parameters were measured for Cobalt and also the variation of emf and inductance are examined and reported in detail by taking ferromagnetic Cobalt material as core of a secondary solenoid when subjected to thermal treatment.
