English Dictionary

Einstein–de Haas effect

固有名詞

(physics) A physical phenomenon in which a change in the magnetic moment of a free body causes the body to rotate, as a consequence of the conservation of angular momentum.

日本語の意味

アインシュタイン・ド・ハース効果：自由な物体の磁気モーメントの変化が、角運動量保存則に従い、その物体に回転を引き起こす物理現象

The team measured the Einstein–de Haas effect by observing the minute rotation of a suspended ferromagnetic rod when its magnetization was reversed.

研究チームは、磁化を反転させたときに懸垂した強磁性棒がわずかに回転するのを観察することで、アインシュタイン＝デハース効果を測定した。

意味（1）

(physics) A physical phenomenon in which a change in the magnetic moment of a free body causes the body to rotate, as a consequence of the conservation of angular momentum.

This relation between the magnetic moment and the angular momentum is demonstrated by the Einstein–de Haas effect, discovered in 1915, in which a ferromagnetic rod is suspended vertically, along its axis, by a thin fibre (see Fig 1.2).
