A QMG coil magnet is an application of an oxide bulk high Tc superconductor (HTS) to obtain high magnetic field. The QMG coil with 11 turns is made from a slice of Ag doped Gd-Ba-Cu-O QMG by using precise machining techniques by Nippon Steel Corporation. The magnet is made from 8 layers of the QMG coil and pulsed current is applied in experiments. Loss of the QMG coil magnet is numerically analyzed with an axisymmetric model, and the total loss of one coil is evaluated and discussed during magnetizing and demagnetizing processes.
