A Circular Loop Carrying a Current of 3

question 40

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.If the plane of the loop is oriented parallel to the field,what torque is created by the interaction of the loop current and the field?

• A) 0.017 N⋅m
• B) 0.084 N⋅m
• C) 0.25 N⋅m
• D) 5.8 N⋅m
