    I don't know. We can assume the plates are circular for symmetry's
    sake. Then, in planar mode, we'd be either looking down the coil axis
    with the plates on opposite sides (left/right or top/bottom), or we'd
    be looking at the side of the coil, with the plates above and below.
    Can femm model a coil in either of these orientations?
