Step 1
We need to find the magnitude of the torque acting on a current-carrying loop with a magnetic moment \( \vec{M} \) in a uniform magnetic field \( \vec{B} \). The plane of the loop makes an angle of \( 60^{\circ} \) with the magnetic field. Show more…

The coil of wire in the drawing is a right triangle and is free to rotate about an axis that is attached along side $A C .$ The current in the loop is $I=4.70 \mathrm{A}$ , and the magnetic field (parallel to the plane of the loop and side $A B$ is $B=1.80 \mathrm{T}$ . (a) What is the magnetic moment of the loop, and (b) what is the magnitude of the net torque exerted on the loop by the magnetic field?
Circular Loop A circular loop of wire having a radius of $8.0 \mathrm{~cm}$ carries a current of $0.20$ A. A vector of unit length and parallel to the dipole moment $\vec{\mu}$ of the loop is given by $0.60 \hat{i}-0.80 \hat{j}$. If the loop is located in a uniform magnetic field given by $\vec{B}=$ $(0.25 \mathrm{~T}) \hat{\mathrm{i}}+(0.30 \mathrm{~T}) \mathrm{k}$, find (a) the torque on the loop (in unitvector notation) and (b) the magnetic potential energy of the loop.
