Question

State ampere circuital law and biot savart law

Answer 1

Solution: A. Ampere law states that for any close looped path, the sum of the length elements times the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop.

The relationship between the magnetic field contribution and its source current element is called the Biot-Savart law. The direction of the magnetic field contribution follows the right hand rule illustrated for a straight wire.
