A pinch (or: Bennett pinch [2] (after Willard Harrison Bennett ), electromagnetic pinch, [3] magnetic pinch, [4] pinch effect, [5] or plasma pinch. [6]) is the compression of an electrically conducting filament by magnetic forces, or a device that does such.
May 28, 2024 · The Pinch Effect is a fundamental phenomenon observed in plasma physics, where an electric current traveling through a gas or plasma causes it to become compressed.
Pinch effect, self-constriction of a cylinder of an electrically conducting plasma. When an electric current is passed through a gaseous plasma, a magnetic field is set up that tends to force the current-carrying particles together.

Jun 25, 2024 · The pinch-off voltage in a JFET (Junction Field-Effect Transistor) refers to the gate-source voltage at which the channel between the source and drain terminals becomes completely depleted of charge carriers (electrons or holes).
Aug 28, 2023 · Define the Pinch-off Voltage for a JFET (Junction Field-Effect Transistor). Learn About the Critical Voltage That Controls the Current Flow in a JFET.
Mar 12, 2022 · Pinch effect is the radial force or “pinch” on a conductor carrying an electrical current. For a given diameter wire, the effect is proportional to the square of the current.
Nov 26, 2014 · Enhancement mode is where you must have a positive Vgs for N-Channel device (negative Vgs for P-Channel device) to have Ids > 0. The pinchoff voltage for this device is some Vgs > 0 (N-channel) or Vgs < 0 (P-channel), depending on the particular device.
