The analysis of magnetic field in high temperature bulk superconductors is presented in this paper. The macroscopic field equations were constructed on the basis of the critical state model and levitation forces ware analyzed between permanent magnets (PM) and HTSC using analytical method. The levitation force between permanent magnets (PM) and HTSC calculation were obtained by using Lorentz force equation [1]. The analytical results show that the presented method is comparatively accurate by comparing the measured levitation forces and the calculation ones. Some relations between B(r, t) and levitation force’s hysteresis are investigated.

Prospects Of Application

In recent years increasingly discusses the prospects of application of high-temperature superconductors (HTS) as the winding current-carrying elements of magnetic systems for various purposes. It seems particularly attractive possibility of such systems at liquid nitrogen temperature. The article describes the prototype of module of the magnetic system which is made on the basis of high-temperature superconducting tapes, designed for the installation and testing on a working model of a static levitation. In the working model levitation of the platform carried by the interaction of the magnetic field of the assembly of permanent magnets mounted on the platform with a field similar to assemblies located in the track structure. Compact HTS module replaces the two assemblies of permanent magnets mounted on the platform. Each block of the module represents HTS racetrack coil with current inputs, power structure, positioning system and bracing which is placed in a cryostat, providing at minimum wall thickness of the required mechanical strength and thermal insulation at liquid nitrogen temperature. The prototype of unified superconducting module successfully passed preliminary tests.

Applied Fields

The exponential model is proposed for levitation force calculations of high temperature superconductors in place of Bean model according to the Exponential relationship between the critical current density and applied field. The calculated results are larger than the experimental results in both symmetrical and unsymmetrical applied fields. The normalization curves agree well in the symmetrical applied field, however, they much differ in the unsymmetrical applied field.

The article describes the creation of an experimental setup to investigate the effect of magnetostatic levitation using magnetic rail (as a base) and platform with permanent magnets in combination with bulk high-temperature superconductors of the 2nd generation. The article provides evidence of the stability of the hybrid pole, the measurement results of the vertical and lateral forces and the dependence of the levitation gap of the sequence of operations of cooling high-temperature superconductors of the 2nd generation. The article provides evidence of the ability to achieve static levitation with a gap of more than 10 mm when using bulk high-temperature superconductors of the 2nd generation and the efficiency of their application to provide lateral stabilization.
