Hysteresis graph testingThis is a thorough test where the magnet is magnetised and demagnetised within a closed circuit situation and a value for Br Hc and (BH)max are obtained. These relate to maximum amount of magnetism in the closed circuit magnet the resistance to being demagnetised and the total energy within the magnet.
