Abstract: The coupling process of magnetic field and shaped charge jet is analyzed, and an equation of rotation motion of the shaped charge jet particles in the presence of magnetic field is established in the case of small angle rotation. On this basis, a simulation method is used to study the characteristics of force and torque of jet particles in magnetic field by the software Ansoft Maxwell, and the experimental verification is also carried out. The research result show that the equation of rotation motion of the shaped charge jet particles in magnetic field could well describe the process of magnetic field inhibiting their rotation, and the numerical simulation of the force and torque of particles in magnetic field also reflects the property of inhibition. The experimental results indicate that the rotation of slug is inhibited and modified under the action of magnetic field, and the axis of slug can remain aligned with the axis of crater penetrated by the jet under the action of magnetic field.
