(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A long, straight wire carries a current of I1 = 15.8 A. Next to the wire is a square loop with sides L = 1.17 m in length. d = 1.42 m, as shown in the figure below.

The loop carries a current of I2 = 2.66 A in a direction parallel to the wire. Calculate the magnitude of the net force acting on the loop.

2. Relevant equations

The equation i have used is Force = I2*L*[(μ0*I1)/(2*pi*d)]

3. The attempt at a solution

Because i am looking for force of the loop, here are my numbers plugged in:

Force = 2.66*1.17*[(μ0*15.8A)/(2*3.14*1.42m)]

= 6.93*10^-6N, answer is incorrect

I am stumped.. any help would be greatly appreciated, thanks!!
