The figure shows a current loop ABCDEFA carrying a current i = 3.82 A. The sides of the loop are parallel to the coordinate axes shown, with AB = 18.9 cm, BC = 30.6 cm, and FA = 10.1 cm. In unit-vector notation, what is the magnetic dipole moment of this loop? (Hint: Imagine equal and opposite currents i in the line segment AD; then treat the two rectangular loops ABCDA and ADEFA.)
