3-D finite element analysis of dynamic characteristics of electromagnet with permanent magnets

There are many kinds of electromagnets for various kinds of fields. The electromagnet with permanent magnets in this paper is one of them in order to improve energy saving. The distribution of flux density is very complex when the voltage is applied to the coil of the electromagnet with permanent magnets. In this paper, the operating characteristics of the electromagnet with permanent magnets are analyzed using the three-dimensional finite element method
