Numerical investigations on influence of hole on permanent magnet method

In the present study, the influence of hole on permanent magnet method is numerically investigated. Recently, permanent magnet method have been proposed for measuring the critical current density. In this paper, a numerical code for analyzing the shielding current density has been developed, and the permanent magnet method for measuring the critical current density has been investigated numerically. In addition, the influence of hole in the HTS on the proportionality of the electromagnetic force and the critical current density is numerically investigated.
