Answer 2

In Ampere's circuital law, the purpose of an "Amperian Path" is:

Option (b): Computation of magnetic field intensity.





Amperian path is a closed loop considered such that at every point of the loop, the magnetic field intensity (or the magnetic field) is either directed parallelly to the differential path length with a constant value (not equal to zero), or directed perpendicularly, or is equal to zero. Now, applying Ampere's circuital law we can evaluate the value of magnetic field intensity at each point of the path by easily obtaining the circulation of magnetic field intensity along the path and the total current the loop encloses.

Hence, a specific Amperian Path is selected to calculate the magnetic field intensity at a point on the path. Therefore the correct answer will be Option (b): Computation of magnetic field intensity.

Determination of differential element of path length does not require a particular Amperian path. So option (a) is incorrect flux density is linked with a Gaussian surface. It has no relation with an Amperian path. So option (d) is also incorrect
