The coil is in a uniform magneticfield of 1.00 T, directed in the positive y-direction withB = (1.00 T)j.(a) Calculate the magnetic moment of each loop ofthe coil.(b) Calculate the magnetic moment of the entire coil.(c) Calculate the magnetic torque experienced bythe coil. Clearly identify the direction of thetorque.(d) How will your answers to parts (a) to (c) changeif the direction of the current in the coil isreversed?(e) How will your answers to parts (a) to (c) changeif the direction of the magnetic field is changed toB = (1.00 T)i or B = (1.00 T)k? Explain.(f) The coil rotates from the position where its magneticmoment is parallel to the direction of the magneticfield to the position where its magnetic moment isperpendicular to it. What is the change in the poten-tial energy of the coil? Explain.·2R-100 loopsX
