A Rigid Circular Loop Has a Radius of 0

question 50

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?
