More Information
Summary:The method for manufacturing the Halbach magnet array comprises a) magnetizing at least one first magnetic material piece and at least one second magnetic material piece in a direction parallel to a first direction, and b) magnetizing a third magnetic material piece in a direction parallel to a second direction perpendicular to the first direction, in this order. The first magnetic material piece and the second magnetic material piece are alternately arranged in the second direction with the third magnetic material piece interposed therebetween. The first magnetic material piece adheres to the adjacent third magnetic material piece via a non-magnetic layer with a thickness t1, the second magnetic material piece adhere to the adjacent third magnetic material piece via a non-magnetic layer with a thickness t2, and t1 and t2 satisfy a formula t1<t2.
