Description

Motion of an isolated vortex in a hard superconductors type II has been considered with action of all the forces taken into account. The obtained results have been used to construct vortex trajectory. The equation for vortex motion in the alternating-current field has been solved. Power absorption as a function of frequency of the external alternating current has been calculated. The magnetization of superconducting NbTi plate has been measured to study the behavior of effective conduction in the region of superconducting transition. Dependence of the effective conductance on magnetic field has been calculated. Structure of electric impulse has been measured on the surface of superconducting cylinder by contact method. The results have been used to explain the extreme dynamics of magnetic flux in hard superconductors type II.
