• polarity magnetic system
• permanent magnetism
• air magnetic flux

The work points of the air magnetic flux for the typical two polarity magnetic systems of differential and bridge magnetic system are analyzed and calculated based on the node voltage method of equivalent magnetic circuit in this paper. The universal calculate expressions are sum up. The electromagnetism attractive force for one group work air is derived. The work mechanism for the magnetic holding relay and polarity relay are analyzed. The conclusions are good to analyze the working mechanism of polarity relays.
