Permanent magnet demagnetization at high temperature

Application ID: 153291


Permanent magnet manufacturers test magnets by applying a cyclic temperature load during the design process to assess the resulting thermal demagnetization. The heating process is usually slow enough that the temperature distribution inside the magnet can be considered uniform at any given time. This model simulates the thermal demagnetization effect under such conditions. To consider the effect of a non-uniform temperature variation, heat transfer can be added to the model.
