Operating principles
The MAG series measuring instruments enable the magnetization, adjustment and demagnetisation of all anisotropic and isotropic magnetic materials in all usual sizes. In particular it is possible to magnetize all highly coercive magnetic materials such as Sm2Co17 or plastic composite NdFeB magnets easily and with short pulse intervals. Raw magnets as well as complete workpieces can be magnetized with the magnets integrated into these units.
The systems are suitable for three-shift application in automated production and for use at individual hand-operated workbenches. Depending on the type of housing the systems can be used without any problems both in polluted environments (e.g. in magnet production) and in clean rooms (e.g. in the manufacture of hard disc drives).
