Homework Help: Rotating magnetic flux.

  1. Feb 26, 2012 #1
    1. The problem statement, all variables and given/known data

    Sketch phasors for two alternating fluxes with a 90 degree phase difference. If the two fluxes are directed at right angles, show that the resultant flux rotates.

    2. Relevant equations

    perhpas [itex]N\Phi=BANcosθ[/itex] although I don't think it's necessary

    3. The attempt at a solution

    I've done the phasors, simply two arrows at a right angle to each other (not joined though).

    I think that if the two fluxes are across each other, in an X shape, I add the flux vectors at various points and a circle will form. Is this correct?
