Query: Experimental and theoretical study of AC losses in variable asymmetrical
  magnetic environments   Measurements of AC losses in a HTS-tape placed in between of two bulk
magnetic shields of high permeability were performed by applying calorimetric
techniques for various asymmetrical shielding arrangements. The experiment was
supported by analytical calculations and finite-element simulations of the
field and current distributions, based on the Bean model of the critical state.
The simulated current and field profiles perfectly reproduce the analytic
solutions known for certain shielding geometries. The evaluation of the
consequent AC losses exhibits good agreement with measurements for the central
position of the tape between the magnets but increasing discrepancy when the
tape is approaching the shields. This can be explained by the increasing
contribution of the eddy currents and magnetic hysteresis losses in the
conducting shields.
