Induced Current

  1. Feb 29, 2008 #1
    [SOLVED] Induced Current

    1. The problem statement, all variables and given/known data

    If I have a scenario where one coil is insider another, in which of the following cases will the induced current in the outer coil be the greater?


    3. The attempt at a solution

    I would say when the current in the inner coil is increasing rapidly, but I am not sure.

    I just read that the faster the any changes are carried in setup, the greater the current, this should mean that if the applied current in the inner coil is increased fast, then the current should be greater, (but that would be for the inner), how about the outer.

    I should think so. Because faster the current in the inner one changes, the greater the rate of change of flux in the system, and hence, greater the variation of current in the outer coil.

    ok, so far we both agree it's should be when the applied current in the inner coil is increasing rapidly. anyone else agree to this?
