Einstein–de Haas effect

名词 n.

英文释义

名词 n.
  1. 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).
