Abstract: We study theoretical aspects of the light variability of magnetic chemically-peculiar stars, using HD 37776 and HR 7224 as the test cases for our understanding of the light variability. We are able to reproduce their light curves from the known distribution of surface elements. We show that the light variability of these stars is mainly due to the inhomogeneous surface distribution of overabundant silicon, iron and helium.
