Magnet orientation device and magnet

A magnet orientation device comprising:

• an upper plate disposed on a magnet raw material and having a convex upward arc shape;
• a lower plate disposed below the magnet raw material;
• and
• a plurality of dies disposed at a first side and a second side of the magnet raw material,
• wherein the upper plate comprises a first magnetic region and a first non-magnetic region that surround the first magnetic region,
• wherein the lower plate comprises a second magnetic region and a second non-magnetic region that surround the second magnetic region,
• wherein a lower surface of the first magnetic region provides a plurality of concave upward grooves,
• wherein an upper surface of the second magnetic region provides a plurality of convex upward protrusions,
• wherein each of the plurality of concave upward grooves and the plurality of convex upward protrusions includes a curvature,
• wherein, among the plurality of concave upward grooves, a shape of concave upward grooves adjacent to a first side end and a second side end of the first magnetic region is different from a shape of the other concave upward grooves, and
• wherein, among the plurality of convex upward protrusions, a shape of convex upward protrusions adjacent to a first side end and a second side end of the second magnetic region is different from a shape of the other convex upward protrusions.
