Abstract

We performed numerical simulation of the trapped magnetic field by varying the thickness and the side length of the bulk superconductor, based on the sand-pile model and Biot-Savart law. It was found that the trapped magnetic field density at the center of the sample saturated when the sample thickness exceeds a certain value. Such thickness dependence is explained in terms of the geometrical effect or de-magnetizing effect.
