  • Magnetic variable capacitor
    Patent number: 4312025
    Abstract: A capacitor comprises a resilient strip of magnetic material, such as steel, a strip of non-magnetic material such as brass and a layer of insulation between the two. An end portion of the resilient strip is movable between a position substantially parallel and close to the brass strip and a position as an angle to and spaced further from the brass strip. A magnetic coil or permanent magnet controls the position of the movable end portion of the resilient strip relative to the brass strip to thereby control the capacitance between the two strips.
