Self-Demagnetization of a Cylindrical AlNiCo Magnet

Application ID: 57891


Soft permanent magnets like AlNiCo are easily demagnetized if handled incorrectly. This is a demonstration of how to model the self-demagnetization of a cylindrical AlNiCo magnet when moved out of its associated/protective magnetic circuit. The modeling is performed in three steps:

  1. The soft magnet protected by the magnetic circuit.
  2. The self-demagnetization of the soft magnet when moved into free air.
  3. The linear recoil model when moved back into the magnetic circuit.
