Ampere's Law 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.

In classical electromagnetism, Ampère's circuital law , discovered by André-Marie Ampère in 1826, relates the integrated magnetic field around a closed loop to the electric current passing through t...

Ampere's law is the magnetic equivalent of Gauss's law. It is different in that it refers to a closed loop and the surface enclosed by it (rather than a closed surface and the volume enclosed by it, as is the case with Gauss's Law).

  Ampere's law allows us to write down a single equation that describes all of the ways that electric current can make magnetic field. But, just as with Gauss's law, this single equation is very difficult to solve.

Biot-Savart law and Ampere's law ... At distance R above the wire, the magnetic field B will be toward you, and Ampere's law says that; B(2p R) = m oI, because you can circle around the wire in a path with radius R, so B is constant on that path, and the path length is 2p R. Now let us find B by Biot-Savart.

According to Ampere's law, the flux of electric current through a straight wire produces a "circulation" of magnetic field, B⟶ , on a circular path around the wire. In terms of symbols, we get ... If we combine this statement, generalized to hold for any surface, with Stokes' theorem applied to the vector...
