We study the orbital magnetic response of mesoscopic metallic systems. The response in singly (Landau) and multiply (Aharonov-Bohm) connected geometries is considered. It is argued that the absence of phase and energy relaxation at the sample boundaries in a typical magnetic measurement has dramatic consequences for the magnitude and the scale of variation of the response with the magnetic flux. We identify several regimes, depending on the strength of the magnetic field and the degree of disorder, and investigate the response in each of them. In particular, we discuss the mesoscopic fluctuations of the response and its average properties including the interaction-localization correction.
