Question

what is Maxwell's cork screw rule ?​

Answer 1

The Maxwell Screw Rules sometime is also called the Maxwell's Corkscrew Rule. Imagine a right handed screw being turn so that it bores its way in the direction of the current in the wire. The direction of rotation gives the direction of the magnetic field.

Answer 2

Imagine driving a corkscrew in the direction of current then the direction of turning of its handle gives the direction of magnetic field lines. It is used to find the magnetic field in a circular loop and straight wire carrying current.

Imagine a corkscrew held by your hand rotate. the screw head such that its tip advances in the direction of the current in a conductor as shown. the direction in which the thumb or the head of the screw rotates gives. the direction of the magnetic lines of force a magnetic.
