Abstract
An electromagnet structure comprises a magnetic shell having a cavity, a magnetic pole located within the cavity and having a magnetic gap for focusing a magnetic field on a magnetically tunable filter, a conductive coil located within the cavity of the magnetic shell and forming multiple turns around the magnetic pole, and a heater located within the cavity of the magnetic shell and configured to maintain the conductive coil at a substantially constant temperature when the magnetically tunable filter is tuned to different frequencies.
