A circular loop of wire with area AA lies in the xyxy-plane. As viewed along the zz-axis looking in the −z−z-direction toward the origin, a current I is circulating clockwise around the loop. The torque produced by an external magnetic field B⃗ B→ is given by τ⃗ =D(2i^−2j^)τ→=D(2i^−2j^), where DD is a positive constant, and for this orientation of the loop the magnetic potential energy U=−μ⃗ ⋅B⃗ U=−μ→⋅B→ is negative. The magnitude of the magnetic field is B0=13D/IAB0=13D/IA.
