Abstract

The present application discloses a magnetic measurement method for a two-pole deflection magnet, which includes: according to the measurement stroke of the Hall point measuring machine, dividing the magnetic measurement area of ​​the two-pole deflection magnet to be measured into two or more parts less than or equal to the measurement area The magnetic measurement sub-region of the stroke; move each of the magnetic measurement sub-regions to the range of each measurement stroke in turn, measure and obtain the measurement data of each of the magnetic measurement sub-regions, and the measurement data includes the magnetic measurement sub-region The relative coordinates of the relative coordinates and the magnetic field amount under the relative coordinates; according to the corresponding relationship between the absolute coordinates of the magnetic measurement area and the relative coordinates, the measurement data of each of the magnetic measurement sub-areas is combined to obtain the magnetic field of the magnetic measurement area. Measurement data. The above scheme does not need to lengthen the stroke range of the probe rod of the Hall point measuring machine, so it avoids the problem of poor accuracy of the measurement results caused by the decrease in the running accuracy of the probe rod as its stroke increases; the accuracy of the measurement is guaranteed.

Description

technical field [0001] The invention generally relates to the technical field of magnetic field measurement, and in particular to a magnetic measurement method with a two-pole deflection magnet. Background technique [0002] At present, a Hall point measuring machine is generally used to measure the magnetic field of a magnet. The measuring stroke of the Hall point measuring machine is a long rectangular area. For the two-pole long deflection magnet with small bending radius, the measuring stroke of the existing Hall point measuring machine cannot cover the entire magnetic measuring area. In order to be able to measure smoothly , a current practice is to replace the longer probe rod to lengthen the travel range of the probe rod of the Hall point measuring machine. However, as the travel range of the probe rod increases, the running accuracy of the probe rod decreases accordingly. This will directly affect the accuracy of the measurement results.
