Residual magnetization

…Next, if the strength of the magnetic field is reduced, the magnetization also decreases, but even if the magnetic field is reduced to zero, the magnetization does not become zero. The magnetization (OM) at this point is called residual magnetization. If a magnetic field in the opposite direction is further applied and the strength of the magnetic field is increased, the magnetization becomes zero at a certain magnetic field strength, and the magnetic field (OC) at this point is called the coercive force. …

*Some of the terminology that refers to "residual magnetization" is listed below.

…次に磁場の大きさを減少させると磁化は減少するが，磁場を0にしても磁化は0にならない。このときの磁化(OM)を残留磁化residual magnetizationと呼ぶ。さらに逆向きの磁場を加え，磁場の大きさを増加させるとある磁場の大きさで磁化が0になり，このときの磁場(OC)を保磁力coercive forceという。…
