Abstract

In this paper. We experimentally investigated the magnetic properties of YBCO bulk superconductor using AC magnetization method. The sample is 2.8cm wide in a diameter and 1.4cm long. We applied Ac magnetic field parallel to the direction of length of YBCO bulk. It is observed that YBCO bulk has the diamagnetic properties. AC loss calculation of YBCO bulk superconductor was performed by evaluating the total area of magnetization traces. As depends on the frequency and amplitude of the applied magnetic field.
