This specially designed test bench has two magnetization facilities which are current flow and field flux. Four test pieces can be tested at the same time. Test cycles are 4 parts per 16 seconds. Each current flow magnetization circuit is connected to a transformator, which produces peak 2500 amperes AC, effectively 1800 ampere AC current. Longitudinal magnetization is applied by electromagnetic yokes. Each yoke provides up to 15000 ampere turns of magnetizing field flux. Demagnetization is carried out automatically.
