22.4 Ampere's Circuital Law

Figure 5

The mathematical proof of this is beyond the scope of this guide; however it can be said that the equivalence between Biot-Savart and Ampere's Laws will be brought out by determining due to an infinitely long conductor carrying a steady current through it.

Figure 6

In fig.7, the circle in the plane is perpendicular to the plane of diagram, and is used as an Amperean loop.

\  Applying Ampere's Circuital Law.

Figure 7

Equations (4) and (5) are identical. That is obvious as each gives due to an infinitely long conductor. Thus equivalence is established between the Biot-Savart and Ampere's Laws.
