Question

A square loop of wire carries a current and is located in a uniform magnetic field.

A square loop of wire carries a current and is located in a uniform magnetic field. The left side of the loop is aligned and attached to a fixed axis (dashed line in figure). When the plane of the loop is parallel to the magnetic field in the position shown, what is the magnitude of the torque exerted on the loop about the axis of rotation, which is along the left side of the square as indicated by the dashed line in the figure? Answer in units of N m.

Explanation / Answer

torque exerted on the loop about the axis of rotation is given by

T=NIAB

T=1*4.4*(0.36*0.36)*0.2

T=0.114 N-m
