This article takes electromagnet as the research objectives and introduce the function of electromagnet in circuit breaker with spring operating mechanism.According to the specific structure of the solenoid electromagnet
the magnetic circuit of the electromagnet is calculated
and its magnetic potential
magnetic flux
magnetic induction intensity and suction force are analyzed.Finally
the time characteristics of the electromagnet are discussed in combination with experiments
which provides a reference for the calculation and optimization of the electromagnet ’ s characteristics.
