Abstract
The utility model relates to a quasi magnetic monopole model and belongs to the technical field of physics application. A hollow hemispherical permanent magnet is manufactured by variable magnetic shaft orientation pressing, forming, sintering and magnetizing; a hollow spherical permanent magnet is formed by butting and combining two hollow hemispherical permanent magnets; high magnetic permeability materials are arranged on the inner and outer surfaces of the hollow spherical permanent magnet; the outer edge of the hemispherical bottom of the hollow hemispherical permanent magnet has inverted chamfering; and variable magnetic shaft orientation magnetizing is performed at the inverted chamfering. According to the quasi magnetic monopole model, a stray heteropolar magnetic field at the periphery of the magnetic monopole is eliminated, so that the monopole on the outer surface is uniform in magnetic field, and a magnetic monopole model which is strict and practical is manufactured.
Description
Technical field
The utility model relates to a kind of accurate magnetic monopole model, belongs to the physics applied technical field.
Background technology
Seeking magnetic monopole and unremitting effort the microworld physicists always, but having no resolution so far.And people simulate according to the characteristic of magnetic monopole in macrocosm, design multiple model.As Dec in 2010 Granted publication on the 1st Chinese patent " magnetic monopole " (CN201663026U), it " be that an appearance that is assembled by permanent magnetism tooth body is a magnetic pole, the inner magnetic monopole that wraps up again another magnetic pole simulation." in fact it is a magnet with magnetic pole of periphery demonstration of definite shape.Strictly speaking, according to this configuration and packaging technology, the spuious heteropole magnetic field that the outside surface of this unipolar magnets all can be measured exists, and the magnetic field of its outside surface is inhomogeneous, especially at the seam crossing of each several part assembling.
The utility model content
For making up the deficiencies in the prior art, the utility model provides a kind of accurate magnetic monopole model, with the structure that minimum magnetic assembly is assembled and outside surface arranges equal magnetic conductance magnetic material within it, and the technique that becomes the magnetic axis magnetizing direction, produce magnetic monopole model stricti jurise and the energy practicality.
To achieve these goals, the utility model is taked following technical scheme, a kind of accurate magnetic monopole model, make the hollow hemisphere permanent magnet after becoming the compressing and sintering of magnetic axis orientation, magnetizing, be combined to form the hollow ball permanent magnet by two hollow hemisphere permanent magnet docking, inside and outside surface at the hollow ball permanent magnet all arranges high permeability material, outer rim rounding at the bottom of the hemisphere of described hollow hemisphere permanent magnet, do at the rounding place and become magnetic axis and magnetize, and the depression that forms at the rounding place is filled non-magnet material.
The beneficial effects of the utility model are, owing to only there being two magnetic assemblys to assemble, reduce to greatest extent the combination gap, thereby the possibility that makes outer surface of spheroid produce spuious heteropole magnetic field drops to minimum; Due to the outer rim rounding at the bottom of the hemisphere of hollow hemisphere permanent magnet, and do at the rounding place and become magnetic axis magnetizing direction orientation, make the stray magnetic field toe-in of the faying face of two hollow hemisphere permanent magnets, make the outside surface of ball not show opposite pole; Because the surfaces externally and internally at the hollow ball permanent magnet all arranges high permeability material, make spheroid periphery one pole magnetic more even; It is accurate magnetic monopole model between 1000mm-3mm that the technical solution of the utility model can be made diameter, and range of application is more extensive.
Description of drawings
Fig. 1 is one-piece construction constructed profile of the present utility model, and Fig. 2 is the sectional view of hollow hemisphere permanent magnet, and Fig. 3 is two sectional views after hollow hemisphere permanent magnet docking combination.In figure, 1---permanent magnet, 2a, 2b---high permeability material, 3---rounding, G---the center radiation orientation that magnetizes, G '---the change magnetic axis orientation that magnetizes.
Embodiment
As shown in drawings, the accurate magnetic monopole model of the utility model is combined by two hollow hemisphere permanent magnets 1 docking, within it, outside surface all arranges high permeability material layer 2 a, 2 b.The radius of the hollow hemisphere permanent magnet 1 of the present embodiment is 6mm, high permeability material layer 2 a of its inside surface are an integral hollow ball, in general, when the radius of hollow hemisphere permanent magnet 1 hour, as less than 3mm the time, the high permeability material of its inside surface should be solid sphere.The making of hollow hemisphere permanent magnet 1 is that through becoming magnetic axis orientation compressing (the overall process anoxybiotic carries out under the high-purity argon gas environment), sintering, timeliness are put into the magnet charger that becomes magnetic axis magnetic field and auxiliary magnetic pole and magnetized after the operations such as mechanical shaping.Outer rim at the bottom of the hemisphere of hollow hemisphere permanent magnet 1 is done rounding 3, and rounding 3 places are done becomes magnetic axis magnetizing direction orientation, and the depression that forms at rounding 3 places is filled non-magnet material.
