Induction Heating Coil Shape

  1. Dec 6, 2016 #1
    Goodmornig everybody,
    I'm working on the design of a power converter for high frequency induction heating. The induction coil should be a flat spiral (pancake) with a rectangular shape, but my customer would like to design it as shown in the following picture. I think it will not work because that way magnetic field lines are canceled. What do you think ?
    Thank you.
    Davide

    Welcome to the PF.

    Your thoughts are correct. That will not
    work. It needs to be a 3-D coil, or at least a 2-D coil.
