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.
Flaky morphology of magnetic alloy particle material can raise its natural resonance frequency because of strong shape anisotropy, which is advantageous to acquiring high microwave permeability.
