Asquare 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?
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 .
