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.
A measuring method for pulse permeability was briefly introduced in this paper. Pulse permeability of some magnetic materials was measured under different conditions, and the results were given.
