Abstract:This paper describes a method to calculate inductances of magnetic switches, toroidal coils wound on ring‐shaped cores of non‐linear magnetic material. To check the described theory, measurements have been carried out on the inductance of magnetic switches in the saturated state. Most text books give expressions for the inductance, but for the critical applications presented here a better approximation is required. Therefore to calculate the inductance of a toroid, the main and three additional types of flux h… Show more
