Popis:	Using magneto-optical visualization of the flux in superconductors, the dependence of the flux distributions on the rate of sweep of the external magnetic field (`dynamic relaxation') is directly observed for thin films patterned into small rectangles. The differences in the flux patterns are clearly detectable especially when the sample is not fully penetrated. Various ways of analysing the flux patterns in order to determine the dynamic relaxation rate Q quantitatively from the magneto-optical images are discussed.
