The hyperfine interaction due to the orbital magnetic moment of conduction electrons is investigated. The effect can be split into two parts. One part is due to the long-range component of the interaction and it depends only on the macroscopic properties of the solid, i.e. on the magnetic susceptibility. This part depends on the shape of the sample via the demagnetizing factors; its magnitude is small, but the effect may be observable in a substance with very large g factor. The second part arises from the short-range component of the interaction and is the analogue of the atomic orbital hyperfine interaction; it reduces to it when the atoms are separated.
