(under the class definition) Subject matter wherein the amplifier includes means for applying or varying a magnetic field, and an electrical resistor subjected to such field or varying field in such manner that the value of the resistance transverse to the magnetic field changes, thus comprising a Hall Effect Device; such Hall Effect Device may comprise the amplifying device, per se, or may be included as a unilateralizing means (gyrator) to insure unilateral operation of the amplifier.
