and the sample supporting plate 8 is fixed on the U-shaped supporting seat and penetrates through the circular space in the middle of the coil group, and the sample supporting plate 8 is parallel to the guide rod 3.
The working principle is as follows: firstly, adjusting the distance between a first coil group 71 and a second coil group 72 according to the type of a required magnetic field, wherein when the Helmholtz coil magnetic field needs to be generated, the distance between two parallel coils is adjusted to be equal to the radius of the coils; when a Maxwell uniform gradient magnetic field needs to be generated, the distance between the two magnetic field coil groups is adjusted to be 1.732 times of the radius of the coil. Then, determining the directions of currents applied to the first coil group 71 and the second coil group 72 according to the type of the generated magnetic field, wherein when the Helmholtz coil magnetic field needs to be generated, the directions of the currents applied to the first coil group 71 and the second coil group 72 are the same; when a maxwell homogeneity gradient magnetic field or a gradient magnetic field needs to be generated, the first coil set 71 and the second coil set 72 apply current in opposite directions. The sample support 8 is used for placing the test sample 6, and when the device works, a magnetic field required by people can be generated within a certain range, so that the magnetic effect test experiment can be carried out on the test sample 6 placed on the sample support plate 8.
Among the above-mentioned technical scheme, U-shaped supporting seat includes: the upper surface of the bottom plate 11 is fixedly connected with two side plates 2, and the lower surface of the bottom plate 11 is fixedly connected with 4 foot pads 1; the two ends of the guide rod 3 are fixedly connected with the two side plates 2 respectively, and the two ends of the sample supporting plate 8 are fixedly connected with the two side plates 2 respectively.
