The Impact Induced Demagnetization Mechanism in NdFeB Permanent Magnets

“…[6] Wang suggested that an anomalous phenomenon of ultrasonic velocity and attenuation coefficient at low temperatures is caused by the abrupt change of the direction of magnetization. [7] From the discovery of the Nd 2 Fe 14 B compound in 1983, [8,9] explosive driven pulsed power generators based on Nd 2 Fe 14 B alloys were considered as the most effective compact pulsed power sources. [10−12] Thus, researchers started to be interested in pulsed power sources based on Nd 2 Fe 14 B permanent magnets.…”
