Explanation:

What is stated by Ampere’s Circuital Law? The formula for this is a closed loop integral. The integral of magnetic field density (B) along an imaginary closed path is equal to the product of current enclosed by the path and permeability of the medium. Line integral to the magnetic field of the coil = μo times the current passing through it. It is mathematically expressed as

∫ B.dl = μo I

Here μo = permeability of free space = 4 π × 10-15 N/ A2 and ∫ B.dl = line integral of B around a closed path.
