The phenomenon of light confinement in an isolated quantum dot, provided by the resonant nature of exciton in QD and diffraction of electromagnetic waves at the dot boundary, is discussed. It has been shown that at a certain condition the quantum dot behaves as a microcavity those eigenmodes manifest themselves as additional, geometrical, resonances in the quantum dot electromagnetic response. The effect of induced magnetization of quantum dot is predicted and illustrated by the example of magnetic resonances in spherical quantum dots.
