Einstein – de Haas Experiment

  1. Oct 26, 2004 #1
    When you apply a vertical magnetic field to a metallic cylinder suspended by a string it begins to rotate. Why does it do so?

    Doesn't anyone know about this?
    Doesn't it have something to do with the fact that a metal rod in which electricity is flowing starts to vibrate when put under a vertical magnetic field?
    I've heard something about determinants of two vectors where one is the force by the magnetic field acting vertically and the other from the magnetic field withing the metal rod. The determinant of these two go on a third axis as to make the vectors 3D, and hence it starts to vibrate. Or? Any similarities or am I on the wrong path?
