MANUFACTURING METHOD FOR MAGNET AND MAGNET

摘要

A manufacturing method for a magnet 6 is provided which includes molding, under pressure, magnetic powder 1 in a form of secondary particles resulting from aggregation of primary particles, to obtain a molding 5. A ratio of an average particle size (D50) of the primary particles to a maximum particle size of the secondary particles is 1:150 to 1:200. The magnet 6 in the invention is manufactured by the manufacturing method for a magnet in the invention. The invention allows manufacture of the molding 5 and the magnet 6 in both of which the magnetic powder 1 is densely compressed. The magnet 6 has a high residual magnetic flux density.
