Question

We draw an Amperian loop within a wire that carries current uniformly across its circular cross-sectional area. Which describes the value of the integral in Ampere’s law?

It is proportional to the total current.

It is inversely proportional to the total current.

It is proportional to the current encircled by the loop.

It is inversely proportional to the current encircled by the loop.

It is proportional to the current that is outside the loop.

It is inversely proportional to the current that is outside the loop.
