Abstract
De-magnetization protection is provided for electro-permanent magnets during information handling system manufacture and use by monitoring thermal conditions at the information handling systems to detect a thermal state associated with de-magnetization and commanding the electro-permanent magnets to an off state so that both magnets in the electro-permanent magnet have opposing polarities. The opposing polarities tend to stabilize magnet polarity to prevent de-magnetization during increased temperatures. Normal operations are then re-enabled once temperatures decrease.
