Dynamics of a magnetic particle in an oscillating magnetic field

The dynamics of a magnetic particle of moment m in an oscillating magnetic field H has a qualitative dependence on the magnetization model. There are sustained oscillations for a particle with a permanent dipole. The particle is static for an induced dipole with no hysteresis. For an induced dipole with hysteresis, there is a transition between oscillations with a magnetic moment oscillating about a particle axis, and a magnetic moment flipping relative to the particle axis.
