Pinch phenomenon
The Z-pinch is an application of the Lorentz force, in which a current-carrying conductor in a magnetic field experiences a force. One example of the Lorentz force is that, if two parallel wires are carrying current in the same direction, the wires will be pulled toward each other. In a Z-pinch machine the wires are replaced by a plasma, which can be thought of as many current-carrying wires. When a current is run through the plasma, the particles in the plasma are pulled toward ea… WebJun 7, 2016 · Pinch off occurs when the the inverted charge near the drain edge under the gate edge becomes zero at the VDS=VDSAT=VGS-Vtn for n-MOSt. Which means one has to put on the drain a voltage equals to...
