question 5

Essay

A rigid circular loop has a radius of 0.20 m and is in the xy-plane. A clockwise current I is carried by the loop, as shown. The magnitude of the magnetic moment of the loop is
0.75 A · m². A uniform external magnetic field, B = 0.20 T in the positive x-direction, is present. (a) What is the current in the loop?
(b) Find the magnitude of the magnetic torque exerted on the loop.
(c) If the loop is released from rest, in what direction will points a and c initially move?
