permanent magnet

Calamit produces two types of electro-permanent devices: The EPC model is always magnetized and uses current to change orientation of the magnetic field (max insertion time = 10 sec). When current is not inserted, it goes back to be a normal permanent magnet. The EPF type totally magnetizes and demagnetizes the magnetswithin the electro-magnetic module. This results in total security for the lifting and transport of any metal particular that will therefore not risk being accidentally let go due to lack of current. The relative switchboards for the transformation in alternate current are available upon request.
