permanent magnetic cylindrical pinch
Pinch plasma physics - Wikipedia
A pinch is the compression of an electrically conducting filament by magnetic forces. a current-carrying magnetic-field-aligned cylindrical plasma pinch undergoing balance inwards magnetic pressure, and the total pressure is constant.
In a z-pinch, the current is axial in the z direction in a cylindrical coordinate system balance inwards magnetic pressure, and the total pressure is constant.
