A number of wires carry currents into or out of the page as indicated in the figure. 5I 101 0151 91 141 SH Loop 2 Loop Part 1: (a) Using loop 1 for Ampère's law, what is the net current through the interior of the loop? net I nto the screen. Part 2 out of 2 Re (b) Repeat for loop 2. 1 out of screen net 7 attempts left Check my work Next part

Answer 1

For loop 1, the inward currents are 10I and 14I. The outward current is 15I, so, the net current through the loop 1 is,

I net = 10I+14I-15I = 9I into the screen.

For loop 2, the inward current is 7I and outward current is 15I, so, the net current through loop 2 is,

I net =15I-7I =8I Out of the screen.
