Chapter 27, Problem 27.39(choose chapter or problem)
(II) A 15-loop circular coil 22 cm in diameter lies in the xyplane. The current in each loop of the coil is 7.6 A clockwise,and an external magnetic field B = (0.55i + 0.60j - 0.65k) Tpasses through the coil. Determine (a) the magneticmoment of the coil, jl; (b) the torque on the coil due to theexternal magnetic field; (c) the potential energy U of thecoil in the field (take the same zero for U as we did in ourdiscussion of Fig. 27-22).
