This is a brief review of the theoretical analysis of the interesting magnetization dynamics observed in experiments, when a magnetic material is subjected to magnetic field pulse for a very short time. The explanation of inertia-like dynamics in the post-pulsing period is explained in terms of a redistribution of magnetic energy among the different terms of the effective magnetic Hamiltonian. Then it is clarified if there is at all inertial effects which is important in the context of magnetization dynamics and where from it originates. A new equation for magnetization dynamics is proposed. Finally, it has been outlined how the different relevant quantities such as damping and moment of inertia tensor can be calculated from the first-principles.
