in this problem we'll look at a square loop of wire, L is 3mm and W is 4mm, which is rotating in a constant, 8T magnetic field. the loop has 25 turns. a. for parts a-c assume loop has constant current of 80A, moving clockwise around the loop. what is the magnetic moment of the loop? b. the normal of the loop wire is initially perpendicular to the magnetic field direction. describe the motion of the loop of wire when it is released in this position. what direction will it turn? c. what is the torque (magnitude) on the loop when the normal makes a 35 degree angle with the magnetic field?

a. for parts a-c assume loop has constant current of 80A, moving clockwise around the loop. what is the magnetic moment of the loop?
b. the normal of the loop wire is initially perpendicular to the magnetic field direction. describe the motion of the loop of wire when it is released in this position. what direction will it turn?
c. what is the torque (magnitude) on the loop when the normal makes a 35 degree angle with the magnetic field?
d. now assume the loop is connected to a generator (no longer constant 80A) that rotates the loop at a constant speed of 80m/s (with the right side of the loop rotating into the page, and the left side out of the page.) how much torque does the generator have to provide to the liip, when the normal makes a 35 degree angle with the magnetic field, to maintain speed of 80m/s?
e. what direction is the torque in part d?
