The critical state with a magnetic field dependent critical current density jc(B) has been calculated numerically in superconducting tapes, for magnetic fields above the full penetration field. By using a finite element computation, the magnetic field profiles and the current distribution in the tapes have been calculated both for monofilamentary and for multifilamentary tapes with several aspect ratio of the filaments. Particular attention has been paid to the investigation of the effects of the sample geometry and of the jc(B) dependence on the field profiles and on the hysteresis loop.

The Magnetic Field

The paper presents research on magnetic field exciters dedicated to testing magnetocaloric materials (MCMs) as well as used in the design process of magnetic refrigeration systems. An important element of the proposed test stand is the system of magnetic field excitation. It should provide a homogeneous magnetic field with a controllable value of its intensity in the MCM testing region. Several concepts of a magnetic circuit when designing the field exciters have been proposed and evaluated. In the MCM testing region of the proposed exciters, the magnetic field is controlled by changing the structure of the magnetic circuit. A precise 3D field model of electromagnetic phenomena has been developed in the professional finite element method (FEM) package and used to design and analyze the exciters. The obtained results of the calculations of the magnetic field distribution in the working area were compared with the results of the measurements carried out on the exciter prototype. The conclusions resulting from the conducted research are presented and discussed.
