Abstract
The method for manufacturing the Halbach magnet array includes the steps of: (a) magnetizing at least two first magnetic material pieces in a direction parallel to a first direction, and (b) magnetizing at least one second magnetic material piece in a direction parallel to a second direction perpendicular to the first direction, in this order. In the step (a), the first magnetic material pieces and the second magnetic material piece are alternately arranged in the second direction with the first magnetic material pieces being each adhered to the adjacent second magnetic material piece, and the magnetization is performed under a condition in which a residual magnetization ratio rof the first magnetic material pieces is higher than a residual magnetization ratio rof the second magnetic material piece.
