✦ Synopsis

On the basis of theoretical analysis expressions have been derived suitable for calculating the hysteresis losses in the presence of variable and constant components of both external magnetic field and transport current in a superconducting layer. The calculation scheme can be applied to any arbitrary shape of the field variation cycle, provided the variable components of the field and current are proportional. It has been assumed that the critical current density is dependent only on the external field. For the more common forms of this relationship the results have been expressed in an analytical form. Application of the results is illustrated by calculating the losses in a superconducting solenoid under variable current in the winding and the external field.

The magnetization of hollow superconducting filaments in a perpendicular applied field is calculated numerically using a mathematical model. With this model the hysteresis losses over a closed cycle of the applied field, as well as the instantaneous power dissipation in the filament, can be calculat

This technique is based on an XY display of the hysteresis loop of a magnet," the hystere ~ sis loss is proportional to the loop area. It is shown that the shape and area of the loop are simply related to the short sample properties of the superconductor, Extraneoos effects in a magnet can sometimes

## Abstract New materials such as High‐Temperature‐Super‐Conductors (HTSC) have new properties like “magnetic field penetration” ‐ as well as “flux creep” as also as “trapped field”. They will be researched by test results of several 3‐phase self‐starting HTSC‐hysteresis motors from 50 W to 1.0 kW
