Thermomagnetic characteristics of cores composed of temperature-sensitive magnetic materials

Analytical and experimental results of thermomagnetic characteristics of cores composed of temperature-sensitive magnetic materials, such as flux density, coercive force and permeability, are discussed in this paper. The hysteresis loops of the composed cores were analyzed according to a graphical method based on a simple assumption. The theoretical values and experimental ones show a good agreement. A useful magnetic characteristic, which would not be achieved by any of the components alone, was obtained.
