A Circular Loop Carrying a Current of 3

Multiple Choice

A circular loop carrying a current of 3.0 A is oriented in a magnetic field of 0.35 T.The loop has an area of 0.24 m² and is mounted on an axis,perpendicular to the magnetic field,which allows the loop to rotate.What is the torque on the loop when its plane is oriented at a 50° angle to the field?

A) 4.6 N⋅m
B) 0.16 N⋅m
C) 0.076 N⋅m
D) 0.23 N⋅m
