1. The problem statement, all variables and given/known data A square loop of wire with side length a carries a current I1 . The center of the loop is located a distance d from an infinite wire carrying a current I2. The infinite wire and loop are in the same plane; two sides of the square loop are parallel to the wire and two are perpendicular as shown. 1. What is the magnitude, F , of the net force on the loop? I got that one, which is F= I1*a*uo*I2*((1/2pi(d-0.5a)-(1/2pi(d+0.5a)) 2. The magnetic moment m of a current loop is defined as the vector whose magnitude equals the area of the loop times the magnitude of the current flowing in it (m=IA), and whose direction is perpendicular to the plane in which the current flows. Find the magnitude, F , of the force on the loop from Part A in terms of the magnitude of its magnetic moment. Express in terms of m,I2 ,a ,d , and uo . 2. Relevant equations 3. The attempt at a solution F= I1*a*uo*I2*((1/2pi(d-0.5a)-(1/2pi(d+0.5a)) since m=I/A, then I= m/A F = (m/A)*a*uo*I2*((1/2pi(d-0.5a)-(1/2pi(d+0.5a)) Did I do it correct? Thank you..
