Abstract:
1. An electro permanent magnetic system ( 10 ) for anchoring ferromagnetic material comprising: an electro permanent magnetic module ( 12 ), a control unit ( 11 ) for said electro permanent magnetic module ( 12 ), an electrical connection system ( 13 ) between said control unit ( 11 ) and said electro permanent magnetic module ( 12 ); a magnetization indicator ( 14 ) able (or storing and showing the information relative to the magnetic state of said electro permanent magnetic module ( 12 ); characterised in that said magnetization indicator ( 14 ) is a bistable indicator having two stable states; said magnetization indicator ( 14 ) not requiring electrical power to remain in one or in the other of said two stable states; said magnetization indicator ( 14 ) being electrically powered only in association with the magnetization or demagnetization of said electro permanent magnetic module ( 12 ), to pass from one stable state to the other of said two stable states, without requiring energy for its display.
