1. The problem statement, all variables and given/known data A square loop PQRS carrying a current of 6A is placed near a long wire carrying 10A as shown in the figure. Find the magnetic force on the square loop. 2. Relevant equations F = B * i * l ....................... (1) B = (µ0 * i)/2 π r 3. The attempt at a solution I tried finding out the answer by applying the formulas given above, I tried finding B [by (2) ]and putting it in the equation (1) but I did not get the correct answer. BTW the answer is 1.6 x 10^-5 towards right.
