METHOD OF MANUFACTURING HALBACH MAGNET ARRAY AND HALBACH MAGNET ARRAY

Japanese Patent JP2023018329

A

To provide a method capable of easily manufacturing a Halbach magnet array with a large ratio of the magnetic flux density on the front side and the back side.SOLUTION: The manufacturing method of a Halbach magnet array includes the steps of: (a) magnetizing at least one first magnetic piece and at least one second magnetic piece in a direction parallel to a first direction; and (b) magnetizing a third magnetic piece in a direction parallel to a second direction perpendicular to the first direction. The first magnetic piece and the second magnetic piece are arranged alternately in the second direction with the third magnetic piece interposed therebetween. Each of the first magnetic pieces is joined to the adjacent third magnetic piece via a non-magnetic layer of thickness t1, and each of the second magnetic pieces is joined to the adjacent third magnetic piece via a non-magnetic layer of thickness t2, where t1 and t2 satisfy t1
