The experimental investigation of the levitation force between a PM and MgB2 disk prepared by means of the Reactive Mg Liquid Infiltration is presented. Both FC and ZFC levitation in the temperature range form 21 K to 37 K are considered. The long term behaviour of the levitation force is also investigated. A numerical model is developed in order to investigate the electrodynamics of levitation. The hysteretic behaviour of the levitation force is related to the dynamic of current penetration inside the MgB2 disk by means of the numerical model.

Abstract

The experimental investigation of the levitation force between a PM and MgB2 disk prepared by means of the Reactive Mg Liquid Infiltration is presented. Both FC and ZFC levitation in the temperature range form 21 K to 37 K are considered. The long term behaviour of the levitation force is also investigated. A numerical model is developed in order to investigate the electrodynamics of levitation. The hysteretic behaviour of the levitation force is related to the dynamic of current penetration inside the MgB2 disk by means of the numerical model.
