Abstract

The magnetic flux density and electromagnetic force of different structures of transverse magnetic field（TMF）contacts are analyzed by using simulation method

and the effects of the contact structure on magnetic flux density and electromagnetic force are obtained. The results show that: 1)the maximum value of magnetic flux density of the 16-turn TMF contact is 49.21 m T

the 4-turn TMF contact 63.86 m T

and the screw slotted TMF contact 74.54 m T;2)the arc model’s electromagnetic force of 16-turn TMF contact is 0.042 1 N

the 4-turn TMF contact 0.063 6 N

and the screw slotted TMF contact 0.117 6 N.
