Amperes Circuital Law

Recall Ampere’s Circuital Law:
Ampere’s circuital law states that the line integral of the magnetic field along a closed loop is proportional to the current enclosed by that loop. The mathematical expression is: where:
is the magnetic field,
is the differential length element along the loop,
is the permeability of free space, and
is the current enclosed by the loop.
Step 2: Identify the correct representation of Ampere's law: The correct representation of Ampere’s circuital law is:
