Construction of equivalent magnetic circuit for electromagnet based on 3-D magnetic field

Combined 3-D finite element analysis with the experiments, the magnetic field distribution of the typical flapped electromagnet is investigated. The equivalent magnetic circuit can be constructed based on the simulation results, which inherits the convenience of the traditional magnetic circuit and remains the accuracy of magnetic field analysis. It demonstrates that the proposed method can be utilized to design highly accurate equivalent magnetic circuits of other electromagnets with distinct configurations.
