What is iencl, the current passing through the chosen loop?

The concept passing a current through the loop applies the principle of the Ampere's Law. Ampere's law is commonly applied to electricity and magnetism in which it states that "for any closed loop 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."
