Problem

Consider N parallel wires, each carrying a current i. If an Amperian loop was chosen that enclosed some of the wires, which of the following statements is true:

(a) The line integral ∫ Bdl would be independent of the number of wires enclosed

(b) The line integral ∫ Bdl would be independent of the radius of the Amperian loop (for a given number of wires enclosed)

(c) Halving the number of wires enclosed would reduce the line integral ∫ Bdl by 1/4

(d) The line integral ∫ Bdl is independent of the current in each wire i, only depending on the number of wires enclosed
