1. A system for removing scale or preventing growth of scale comprising:

  • a main unit comprising a generator configured to generate an output signal at a resonant frequency; and

    an immersible, capacitive device comprising a positive conductive element, and a negative conductive element, where the positive conductive element is smaller than the negative conductive element and is at least 0.75 the size of the negative conductive element,the capacitive device configured to generate an electromagnetic output field at the resonant frequency based on the output signal from the main unit and to reduce fringing effects,said main unit further operable to control the electromagnetic output field to at least remove scale or prevent growth of scale in a liquid.
