Barnett effect

Barnett effect

The Barnett effect is the magnetization of a ferromagnetic body when spun on its axis. The magnetization occurs parallel to the axis of spin. It was first reported by S. J. Barnett in 1915. Barnett was motivated by the report of the Einstein-de Haas effect, which describes magnetizing a ferromagnet can induce a mechanical rotation. He instead looked for the opposite effect, ie. a spinning ferromaget changing its magnetization.
