A)4

question 82

Multiple Choice

A circular loop carrying a current of 1.0 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 25 $\degree$ angle to the field?

• A)4.6 N*m
• B)0.076 N*m
• C)0.051 N*m
• D)0.010 N*m
