Abstract: A testing device for study of a magnetized plasma artillery and gunpowder, comprising a pedestal, wherein a top end of the pedestal is provided with a sliding slot for mounting a buffer device, which penetrates through an upper part of the pedestal along a front-rear direction. The sliding slot for mounting the buffer device is internally provided with a buffering slider, which can slide back and forth along the sliding slot for mounting the buffer device. A top end of the buffering slider is provided with a gunpowder combustion chamber fixing groove, which penetrates through an upper part of the buffering slider along the front-rear direction. The gunpowder combustion chamber fixing groove is internally provided with a gunpowder combustion chamber, and an upper part of the gunpowder combustion chamber is provided with a positioning ferrule for fixing the gunpowder combustion chamber.
