Consider a magnetic dipole, M, in the presence of an applied main magnetic field, B=B0k, where k is the unit vector in the z-direction. Assume that initially, M is at equilibrium, has length M0 and is aligned with the main magnetic field (along the z-direction). Describe (or sketch) the position of M in a frame rotating at 0 = B0 for the following sequence of events. Please ignore the effects of any T1 or T2 relaxation. The main field is changed to B=(B0+ delta B)k for a period of time T = pi/gamma * delta(B).
