State Maxwell's right handed cork screw ...

State Maxwell's right handed cork screw rule to find the direction of magnetic field around a current carrying conductor.

Text Solution

Verified by Experts

If a right handed cork screw is rotated such that its tip advances in the direction of current, then the magnetic flux density is given in the direction of rotation of the screw head.
