A review is provided of recent time-resolved scanning Kerr microscopy experiments and micromagnetic simulations of magnetization dynamics in single nanomagnets, and in pairs of dipolar coupled nanomagnets. Two nanomagnet systems are presented. In a single 440 nm square, the effect of the pulsed field amplitude on the relative amplitudes of center- and edge-type confined spin wave modes is explored. In addition, the difference in the damping of dynamics observed in different magnetic ground states is discussed. In pairs of 300 nm disks, the relative effect of structural imperfections and static dipolar fields on the splitting of edge-modes is investigated as a function of disk separation.
