Walker, Halliday & Resnick β Magnetic Fields: Problem 35
35 A circular loop of wire having a radius of 8.0 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 \(0.60\hat{i} - 0.80\hat{j}\). (This unit vector gives the orientation of the magnetic dipole moment vector.) If the loop is located in a uniform magnetic field given by \(\vec{B} = (0.50 \text{ T})\hat{i} + (0.20 \text{ T})\hat{k}\), find (a) the torque on the loop (in unit-vector notation) and (b) the orientation energy of the loop.
