We consider various methods and techniques of measuring electron magnetization and susceptibility, which are used in experimental condensed matter physics. The list of considered methods for macroscopic measurements includes magnetomechanic, electromagnetic, modulation-type, and also thermodynamic methods based on the chemical potential variation measurements. We also consider local methods of magnetic measurements based on the spin Hall effects, NV-centers. Scanning probe magnetometers-microscopes are considered, such as magnetic resonance force microscope, SQUID-microscope, and Hall microscope. The review focuses on spin magnetization measurements of electrons in non-magnetic materials and systems, particularly, in low-dimensional electron systems in semiconductors and in nanosystems, which came to the forefront in recent years.
