Help using electromagnetic induction

  1. Apr 19, 2016 #1
    1. The problem statement, all variables and given/known data
    I am attempting to create a generator using electromagnetic induction. I am using a push pull system to move a bar magnet through a coil to create current. But I am unsure of the dimensions to build it with and when I attempt to use the equation I get stuck. I am looking for around 7.86 volts AC current.

    2. Relevant equations
    v = N × dΦ/dt


    3. The attempt at a solution

    Welcome to the PF.

    You will get a better dΦ/dt if you wave the end of the magnet back and forth in front of the coil, instead of pushing it in and out of the coil. Can you make that change?

    Yes, what method of moving the coil would you suggest?

    What configuration do induction generators use? :smile:

    Basically you have a copper coil and I just have to wave the magnet in front to create a change in magnetic flux.
