Abstract
The utility model discloses a new magnetic induction alignment measuring instrument, which is provided with an outer tube with an open end made of anti-magnetic or magnetic materials. Wherein a translucent screen which is bigger or equal to the cross-section of the outer tube is arranged on the open end and a light source is arranged on the other side of the outer tube. The outer tube has a slit opening wherein a transparent, thin magnetic fluid seal is arranged in the slit opening vertically. The orientation of the diffraction fringes changes in corresponding to the direction of the magnetic and then reflects the strike of the magnetic induction line on the translucent screen. The utility model provides a new method for measuring the direction of magnetic field and has the advantages of the concise structure, the convenient operation, the simple manufacturing process and the relatively low production costs.
Description
Technical field
The utility model relates to a kind of lines of magnetic induction and moves towards measuring instrument.
Background technology
Existing magnetic-field measurement instrument generally is to use magnetoresistance material or makes according to Hall effect, and its production cost is higher.
The utility model content
The purpose of this utility model is to provide a kind of lines of magnetic induction to move towards measuring instrument.It not only can accurately measure the lines of magnetic induction direction, can also measure the continuous trend of lines of magnetic induction.
The technical solution of the utility model is: be provided with the outer tube that one one end opening is made by diamagnetism or paramagnetic material, its openend be equipped with one more than or equal to outside the translucent screen of tube section, be provided with a light source at its other end, on outer tube, have a slit, transparent, thin magnet fluid sealing body of vertical insertion in slit.
Described transparent, thin magnet fluid sealing body is to be packaged with microslide and cover glass or other seal of stablizing magnetic fluid.Adopting plug-in type mainly is to be convenient to change.
Described outer tube should be made by diamagnetism or paramagnetic material, as pottery or other nonferromagnetic material.
Described translucent screen can be frosted glass or other trnaslucent materials.
Described light source can be laser instrument, also can the light source of certain light intensity be arranged for other is difficult for dispersing.
The utility model has adopted the new material magnetic fluid technique, and when not having externally-applied magnetic field, the magnetic-particle in the magnetic fluid is irregular alignment, and orientation is inconsistent.When externally-applied magnetic field, the magnetic-particle in the magnetic fluid is orientated along magnetic direction, forms several finedraws of nothing along magnetic direction, then forms diffraction fringe during light source irradiation, and the bright rays of diffraction is vertical with the finedraw direction; When magnetic direction changed, the finedraw direction changed thereupon, and the orientation of diffraction fringe also with the magnetic direction change respective change takes place, thereby reflected the lines of magnetic induction trend on translucent screen.
The utility model is measured magnetic direction a kind of new method is provided; It simple for structure, easy to use shows very directly perceived; And simple for production, cost of manufacture is relatively low.

Fig. 2 is the utility model inner structure synoptic diagram.
Embodiment
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to accompanying drawing:
Be provided with the outer tube 1 that one one end opening is made by diamagnetism or paramagnetic material, its openend be equipped with one more than or equal to outside the translucent screen 2 of tube section, be provided with a light source 3 at its other end, on outer tube, have a slit 4, transparent, thin magnet fluid sealing body 5 of vertical insertion in slit.The magnet fluid sealing body of present embodiment is to coat samples of magnetic fluids 7 on cover glass 6, microslide 8 is covered get final product.
When not having externally-applied magnetic field, the magnetic-particle in the magnetic fluid 7 is irregular alignment, and orientation is inconsistent.When externally-applied magnetic field, the magnetic-particle in the magnetic fluid is orientated along magnetic direction, forms several finedraws of nothing along magnetic direction, and this moment, light source 3 irradiations then formed diffraction grating at the screen place, and the bright rays of diffraction is vertical with the finedraw direction; When magnetic direction changed, the finedraw direction changed thereupon, and the orientation of diffraction fringe also with the magnetic direction change respective change takes place, thereby reflected the lines of magnetic induction trend on translucent screen 2.
