P-5 please help me with the below problem with step by step explanation clearly. Question -  A 20-loop circular coil 20 cm in diameter lies in the x-y plane. The current in each loop of the coil is 7.6 A clockwise, and an external magnetic field B = (0.80i + 0.60j – 0.65k) T passes through the coil. Determine (a) the magnetic moment of the coil, m, (b) the torque on the coil due to the external magnetic field, (c) the potential energy U of the coil in the field (take the same zero for U as Giancoli in his discussion of Fig. 27-22)

Question -  A 20-loop circular coil 20 cm in diameter lies in the x-y plane. The current in each loop of the coil is 7.6 A clockwise, and an external magnetic field B = (0.80i + 0.60j – 0.65k) T passes through the coil.

Determine (a) the magnetic moment of the coil, m,

(b) the torque on the coil due to the external magnetic field,

(c) the potential energy U of the coil in the field (take the same zero for U as Giancoli in his discussion of Fig. 27-22)
