A 15-loop circular coil 22 cm in diameter lies in the xy plane. 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^)T passes through the coil.

Part A: Determine the x, y, and z projections of the magnetic moment of the coil, μ . Express your answers using two significant figures separated by commas.

Part B: Determine the x, y, and z projections of the torque on the coil due to the external magnetic field. Express your answers using two significant figures separated by commas.

Part C: Determine the potential energy U of the coil in the field (take U =0 at θ = π/2). Express your answer to two significant figures and include the appropriate units.
