Providing a simpler method over the Biot-Savart Law for finding the magnetic field is Amperes Law, which is a combination of the B-S Law, symmetry, and superposition. The result is a neat, easy to use law for finding the magnetic field given off by a current-carrying wire. The only thing to note with this law is that it works using cylindrical symmetry, and so if you had a problem where symmetry wasnt involved you would have to resort to the B-S Law. Now we should be all set with fields and forces, and can move on to the ‘rate of flow of a magnetic field.
Ampere’s Law provides a method of finding the magnetic field due to current flowing in a wire in situations of planar and cylindrical symmetry.
The integral of the magnetic field dotted with the differential of wire around a closed loop is proportional to the current penetrating the closed loop.
