The motion of the plasma with an initial velocity distribution in magnetic mirror field is described by using PIC particle simulation methods, and the particle tracks of the plasma motion in magnetic mirror field can be obtained. It is proved that the magnetic mirror field can confine the motion of plasma and PIC particle simulation method is feasible and effective to simulate the physical process of the plasma in the magnetic mirror field.
