Referring to fig. 1-2, a magnetic field of a table electromagnetic angle display includes an insulating turntable 1 generating a magnetic field, and N iron columns of different sizes mounted on an edge of the insulating turntable 1; the iron column has magnetic force of equidimension not, and insulating carousel center is provided with through-hole 2.
A preparation method of a magnetic field of a desk electromagnetic angle display comprises the following steps:
(1) processing a through hole in the center of the insulating turntable;

Example 1
Referring to fig. 1, a method for preparing a magnetic field of a table electromagnetic angle display includes the following steps:
(1) processing a through hole in the center of the insulating turntable;
(2) processing through holes with diameters from small to large N on the circumferential edge of the insulating turntable;
(3) cutting iron columns with different diameters and the same length;
(4) riveting iron columns into through holes at the circumferential edge of the insulating turntable from small to large according to the diameter, and tightly matching;
(5) and magnetizing the N iron columns by using a magnetizing machine according to the fact that the magnetizing direct current is small to large, and the N iron columns are sequentially magnetized from small to large.
And (4) testing the magnetic field intensity by using a magnetic field detector, wherein the magnetic field intensity is gradually increased according to different distribution of the height of the peripheral bulges.
The capacitor in the magnetizing apparatus is charged with direct-current high-voltage, and then the discharge is carried out through a coil with extremely small resistance. The peak value of the discharge pulse current can reach tens of thousands of amperes. The current pulse generates a strong magnetic field in the coil, and the N iron columns are gradually placed in the coil to be magnetized in the magnetic field, so that the permanent magnetization is realized instantly. According to the principle of magnetic fields related to physics, the N iron columns have different diameters due to small increase, so that the N iron columns have consistent magnetization within the same magnetizing time, but the N iron columns have different magnetic field strengths due to small and large diameters; when N iron columns are pressed into the through hole diameters at the circumferential edge of the insulating turntable, the periphery of the insulating turntable obtains the magnetic field intensity from strong to weak or from weak to strong; if the through hole at the center of the insulating turntable penetrates through the fixture with the rotating shaft and rotates, the parameter-adjusted magnetizing machine is started to work, and current pulses are aligned to the iron columns on the fixture in the coil to magnetize.
And (3) testing the magnetic field intensity by using a magnetic field detector: the magnetic field intensity is distributed in an increasing or decreasing mode.
Example 2
Referring to fig. 2, a method for preparing a magnetic field of a table electromagnetic angle display includes the following steps:
(1) processing a through hole in the center of the insulating turntable;
(2) processing N through holes with the same diameter on the circumferential edge of the insulating turntable;
(3) cutting N iron columns with the same diameter and different lengths;
(4) riveting iron columns into through holes at the circumferential edge of the insulating turntable according to the length from small to large, and tightly matching;
(5) and (3) sequentially magnetizing the N iron columns by using a magnetizing machine according to the magnetizing direct current from small to large.
And (3) testing the magnetic field intensity by using a magnetic field detector: the magnetic field intensity is gradually increased according to the different heights of the peripheral bulges.
When N iron columns have the same diameter and different lengths and are magnetized by a magnetizer to obtain permanent magnetic force, according to the principle of magnetic field related to physics, when the N iron columns are pressed into through holes at the circumferential edge of an insulating turntable from small to large in length, the distance between a magnetic field strength testing point and the plane of the turntable is unchanged, if a central hole of the turntable is penetrated at a rotating shaft and rotates, and a magnetic field strength testing point is arranged at one point at the periphery of the turntable, a probe of the magnetic field strength testing point is close to the highest iron column, so that different iron columns pass through the testing point when the turntable rotates due to different heights, and the magnetic field strength of the magnetic field strength is obtained from strong to weak or from weak to strong.
