A rigid circular loop has a radius of 0.20 m and is in the x-y 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
In figure, the magnitude of the magnetic torque exerted on the loop is closest to
- 0.55 N-m
- 0.15 N-m
- 0.45 N-m
- 0.35 N-m
Answer
(B) 0.15 N-m
