Demagnetization of Permanent Magnet with Respect to the External Magnetic Field and Temperature

Lavanya Vadamodala_20519

In this video, we explore how permanent magnets—widely used in electric machines, sensors, and actuators—can demagnetize under the influence of external magnetic fields and temperature. You’ll gain a clear understanding of:

• The physical principles behind magnet demagnetization
• How external magnetic fields can alter magnetization
• Temperature effects
• B-H curve behavior under thermal and magnetic stress
