Dear Neeraj,

In a n-channel FET a current will flow from source to drain through the channel when the drain is held positive with respect to the source.
If the gate is negative with respect to the source, the channel is squeezed by an electrostatic field and eventually reduces the current through the channel. If the negative gate voltage is increased, current will stop to flow in the channel, or to put it in another way, the channel will be PINCHED OFF. The gate-source voltage at which channel current becomes zero (where the pinch off occurs) is called the pinch off voltage. It is an electrostatic phenomenon
