Not sure how to put this question but heres we go. This is two currents of a coil surrounded by an square amperian loop. Obviously we can see that there are 2 turns of I and the enclosed amount of current is [math]-2\mu_0 I[/math] but how do I actually break up the line integral to show this? I would maybe assume there are four separate lines to the rectangle that all oppose the magnetic field from the currents so summing them up would be 4 or something. Very stupid question I think.
