A new method to obtain information about local surface magnetic properties has been proposed recently. This new technique is based on the idea of measuring magnetic forces with a scanning tunneling force microscope. In this work we present a theoretical analysis of the relevant forces involved in magnetic force microscopy. Recent experiments with high-resolution images of laser-written domains in a magnetic thin film are discussed.
