Abstract

In this work, the trapped magnetic field was calculated using the sand-pile model and Biot-Savart law. The numerical simulation of the trapped magnetic field was performed varying the sample shape and dimensions, distance between the sample surface and observation point. In addition, the magnetic field characteristics of superconducting bulk arrangement in an array was determined. The trapped magnetic field was found to be depending on the sample shape and dimensions and distance between the sample and observation point. It is observed that, when the distance from the surface is larger, the value of the trapped magnetic field decreases, but the variation of the trapped magnetic field becomes small due to averaging the distribution of the trapped magnetic field.
