Question

Consider the square current loop in the figure below. It has an edge length L = 0.22 m and carries a current I = 8.7 A. The magnetic field B = 0.28 T is perpendicular to the plane of the loop. What is the magnitude of the torque on the loop?

________N*M

Consider the square current loop in the figure below. It has an edge length L = 0.22 m and carries a current I = 8.7 A. The magnetic field B = 0.28 T is perpendicular to the plane of the loop. What is the magnitude of the torque on the loop? ________N*M

Explanation / Answer

The magnetic moment of the current loop is directed perpendicular to the plane of the loop.
Because the magnetic moment and external magnetic field are parallel to each other, the magnitude of the torque is zero.
