As shown in Figure 1, the present invention includes babinet 1 and objective table 3, test specimen is fixed on objective table 3,1 both sides of the babinet
Wall centre position is fixed with two metal rings 10 being arranged symmetrically, and the objective table 3 is provided at both ends with what coaxial-symmetrical was arranged
Metal shaft 7, metal shaft 7 are set in two metal rings 10, and 7 diameter of axle of metal shaft is less than 10 internal diameter of metal ring；Loading
3 one end of platform is parallel to be fixed with bar magnet 6, and the two poles of the earth of bar magnet 6 are located at the both sides of metal shaft 7,3 other end of objective table
Both sides of the edge be fixed with two blocks of metal derbies 8.
As depicted in figs. 1 and 2, energization solenoid 11, energization spiral shell are externally provided with close to 1 side wall of babinet of 6 side of bar magnet
Spool 11 is parallel with bar magnet 6 and in sustained height, and 11 middle part of the energization solenoid is through angular transducer 12 and stepping electricity
Machine 13 exports axis connection, and 13 output shaft of stepper motor and metal shaft 7 are coaxially arranged.
As shown in Figure 1, objective table 3 is composed of two layers of insulating materials and metal material, test specimen is attracted magnetically solid
Due to the surface of insulating materials, metal material surface is equipped with is sucked test specimen permanent magnet 14, metal material and permanent magnet for magnetism
It insulate between 14.
As shown in figure 3, close to 8 side of metal derby 1 madial wall of babinet be the center of circle with metal ring 10, two metal derbies 8
Spacing is to be set there are one groove 9 at interval of 1 ° on the circumference of diameter, and 9 size of groove unanimously with metal derby 8, insert by metal derby 8
Enter to be matched with groove 9；Metal derby 8 is more than the depth of groove 9 along the length for being parallel to 7 axis direction of metal shaft, and metal derby 8 is along vertical
Directly match in the size of 7 axis direction of metal shaft and 9 size of groove, to make metal derby be inserted into groove after do not shake, and carry
The end of object platform and box inside wall do not contact.
As shown in Figure 1, babinet 1 be rectangular shape, 1 material of babinet be not with the metal material of magnetic fields, top surface and
Bottom surface is respectively there are one the through-hole 2 being connected with external pipe, and through-hole 2 is threadedly coupled with external pipe, the spiral shell in upper and lower two through hole
Line is oppositely oriented.Import of the through-hole of top surface as fluid, the outlet of the through-hole of bottom surface as fluid.
As depicted in figs. 1 and 2, objective table 3 is equipped with several circular apertures of array distribution, and circular aperture is through insulation
