On this basis, as the permeability of permanent magnetism material is non-linear, two gear wheel's magnetic field is simulated with finite element software, and analysis of the result is carried on.
The methods to measure the magnetic properties of weak-magneticmaterial and non-magneticmaterial, and their application, as well as the MB-2T magnetic balance developed by ourselves are presented.
The single core armored cable in the list are only suitable for use for DC circuit. If used for AC circuit, non-magneticmaterial or armored by reducing magnetic loss structure must be used.
