A Flat Circular Loop Carrying a Current Of $2.0 \mathrm {~A}$

Multiple Choice

A flat circular loop carrying a current of $2.0 \mathrm {~A}$ is in a magnetic field of $3.5 \mathrm {~T}$ . The loop has an area of $0.12 \mathrm {~m} ^ { 2 }$ and its plane is oriented at a $37 ^ { \circ }$ angle to the field. What is the magnitude of the magnetic torque on the loop?

A) $0.67 \mathrm {~N} \cdot \mathrm { m }$
B) $0.10 \mathrm {~N} \cdot \mathrm { m }$
C) $46 \mathrm {~N} \cdot \mathrm { m }$
D) $0.51 \mathrm {~N} \cdot \mathrm { m }$
