Further, described permanent magnet is a slice and in the form of a ring, is positioned over the outside of gyromagnet body and conductor.
Further, described permanent magnet is two, and the symmetrical outside that is positioned over gyromagnet body and conductor.
Further, described permanent magnet is three, and is mutually 120 ° of outsides that are positioned over gyromagnet body and conductor.
Further, described permanent magnet is four, the outside that is positioned over gyromagnet body and conductor symmetrically and evenly.
Further, described permanent magnet forms by cuboid with taking the long limit of cuboid as the fan-shaped of string, or be sector structure or for circular configuration or for cuboid structure or be triangular structure.
Further, the bottom of described cavity has screwed hole, simultaneously has through hole in position corresponding to each parts, to facilitate cover plate to pass through hole by screw, finally screws in screwed hole fastening cover and be combined in the end face opening part of cavity.
Further, described gyromagnet body is spinelle or garnet.
Further, described conductor is beryllium-bronze.
Further, described permanent magnet is ferrite or rare earth.
Magnetic compensation sheet in the present invention, effect is magnetic field intensity compensation or uniform magnetic field, material requirements permeability will be got well, and generally uses Armco iron, stainless iron or stainless steel.
Compared with prior art, the invention has the beneficial effects as follows: adopt after said structure, changed the modes of emplacement of original permanent magnet, optimize in order to be placed on the outside of gyromagnet body stacking up and down, further like this height and the volume of having controlled circulator magnetizes effect fine simultaneously.
