Physics Magnetism,Magnetic Effects Of Current Level: High School

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

a. 5.8 N.m

b. 0.68 N.m

c. 0.084 N.m

d. 0.017 N.m
