ABSTRACT:
A transducer having a cross field polarized permanent magnet mounted for slight pivotal movement within an annular coil winding. The magnet comprises neodymium-iron-boron to provide a compact, lightweight, low inertia and high intensity magnetic field. A magnetic field generated by current in the coil winding influences the permanent magnet to pivot slightly about a horizontal axis and rotate a yoke structure to produce a mechanical output of the transducer. In the preferred embodiment of the invention, the yoke is attached to a spring arm for controlling escape gas pressure from a nozzle to thereby control the pressure of a gas stream.
