In a method of manufacturing a permanent magnet having a curved surface, a permeating material including metal particles and a flux is applied to the curved surface of a magnet. The magnet to which the permeating material is applied is then positioned within a furnace and the furnace is placed in a vacuum or filled with inert gas to volatilize a solvent and the like of the flux contained in the permeating material. The furnace is set to be a temperature within a range of 300 through 500 degrees C. to heat the permeating material. This enables the flux to be carbonized to form reticulated carbon. The furnace is then set to be a temperature within a range of 500 through 800 degrees C. to melt the metal particles in the permeating material, thereby permeating the melted metal particles into the magnet through the reticulated carbon uniformly.
