Title:
METHOD OF MANUFACTURING HALBACH MAGNET ARRAY
Document Type and Number:
Japanese Patent JP2022182315
Kind Code:
A
Abstract:
To provide a method of manufacturing a Halbach magnet array capable of easily manufacturing a Halbach magnet array with a large ratio of magnetic flux density on the front and back surfaces.SOLUTION: The method of manufacturing a Halbach magnet array includes: a step S1 of magnetizing at least two first magnetic pieces in the direction parallel to a first direction; and a step S2 of magnetizing at least one second magnetic piece in a direction parallel to a second direction perpendicular to the first direction in this order. The first magnetic piece and the second magnetic piece are arranged alternately in the second direction, and each first magnetic piece is bonded to the adjacent second magnetic piece. Each of the first magnetic piece and the second magnetic piece has an easy-to-magnetized axis parallel to the first direction and the second direction. The magnetization is performed under the condition that the residual magnetic susceptibility r1 of the first magnetic piece is higher than the residual magnetic susceptibility r2 of the second magnetic piece.SELECTED DRAWING: Figure 2
