    Hi

    Is this correct?
    In the following video: http://www.allaboutcircuits.com/videos/10.html

    The instructor says:
    - QUOTE -
    Okay, magnemotive force, mmf, refers to the energy source that actually creates the flux. It is the magnetic equivalent of, remember we talked about this, emf. Remember that was voltage and this is mmf so it is the magnetic equivalent to voltage. The symbol for magnemotive force is, and it's right here. The unit of measure is ampere-turns, okay and that is Amps* time.
    - UNQUOTE -

    So as time increases, EMF increases, and as time goes towards infinity MMF will go towards infinity?

    Or does the word "time" have another meaning that im not aware of? Could it be refering to turns? If so why is it called time?

    Please help me understand this

    Not time.

    TURNS.

    You, and/or your instructor have used the wrong word.

    That makes a lot more sense than time..

    I suggest that this gets edited into the video, or commented below, if possible
