摘 要：The design and measuring potential of the latest generation of the magnetic scanner called Magscanner-Maglab System（MMS） was presented. It enabled the fast acquisition of 3D signals from magnetic sensors and their visualization as digitalized magnetic images. This system was used for monitoring of a thermal demagnetization process of permanent magnets. The original method and measurement devices were capable for examination of magnetic, mechanical and thermal defects in cylindrical rods made of NdFeB and non-rare earth components. Effectiveness of the method and device was tested for the reference demagnetized magnet dedicated for magnetostrictive actuators.
