A circular ring with area 4.45 cm2 is carrying a current of 12.5 A. The ring, initially at rest, is immersed in a region of uniform magnetic field given by B⃗ =(1.25×10−2T)(12i^+3j^−4k^). The ring is positioned initially such that its magnetic moment orientation is given by μ⃗ i=μ(−0.8i^+0.6j^), where μ is the (positive) magnitude of the magnetic moment. (a) Find the initial magnetic torque on the ring. (b) The ring (which is free to rotate around one diameter) is released...
