A general term for metallic materials that are not magnetized and therefore are not affected by magnetic fields. It is used especially in conjunction with magnetic materials. To use magnetic materials to create devices that utilize magnetism, such as electromagnets, the magnetic materials are arranged in shapes and dimensions appropriate to the purpose, but the parts that support them must be made of nonmagnetic materials. This is to prevent losses such as leakage of magnetic field lines and unnecessary heat generation. In large devices in particular, the forces applied to these parts are large, so materials with excellent strength and toughness are required.

磁化されず,したがって磁界の影響を受けない金属材料の総称。とくに磁性材料といっしょに使用される。磁性材料を用いて電磁石など磁気を利用する装置を作るには,磁性材料を目的に応じた形状寸法に配置するが,そのときにこれらを支持する部分には非磁性の材料を使用しなければならない。これは磁力線の漏れや不要の発熱などの損失を生じないようにするためである。とくに大型の装置ではこの部分に加わる力が大きくなるので,強度,靱性(じんせい)にすぐれたものが必要となる。
