The primary purpose of this paper is to review recent contributions from North American scientists to theory and observations of magnetic domain structures in magnetic minerals common to rocks. Although rock magnetism deals with all the magnetic properties of rocks, a major goal of rock magnetists has been to understand the origins and properties of remanent magnetization (RM). A remanent magnetization is defined as the magnetization that exists in the absence of an external magnetic field. The analyses of RMs (of which there are more than 20 kinds) have led to the numerous, and well‐known, successes of paleomagnetism.
