…The iron cores of AC generators, AC motors, transformers, etc. are made by stacking thin magnetic steel plates that are insulated from each other to avoid eddy current loss. The measured value of eddy current loss is greater than the calculation that assumes that the iron core is uniformly magnetized. This is called eddy current anomaly, and it is known that this is due to eddy currents concentrating at the magnetic wall location in the ferromagnetic material. Induction heating is a heating method that utilizes Joule heat generated by eddy currents. … *Some of the terminology that refers to "eddy current anomaly" is listed below.

…交流発電機,交流電動機,変圧器などの鉄心は,渦電流損失をさけるため,お互いに絶縁した薄い磁性鋼板を重ねて作ってある。渦電流損失の実測値は鉄心が一様に磁化されると仮定した計算より大きく,これを渦電流異常というが,これは強磁性体中の磁壁の場所に渦電流が集中しているためであることが分かっている。なお,渦電流によるジュール熱を利用した加熱法に誘導加熱がある。… ※「渦電流異常」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
