    Hi all,
    I read a question (992) and his answer(994) about the
    meaning of the term "2x frequency" in the Lorentz
    force for frequency problems.
    Now, I understand that if B and J have a fixed
    frequency the force has two component: the steady
    state and the 2*frequency.
    But
    if I make a electro-mechanical transducer, I apply an
    electric current with frequency x and the mechanical
    parts move with double frequency?
