PURPOSE: A method for magnetizing a hemispheric permanent magnet, a hemispheric shell-shaped permanent magnet, and a spheric permanent magnet and an apparatus and a method for a magnetizer are provided to magnetize radially a hemispheric shell or a spheric shell permanent magnet by improving a structure of the magnetizer. CONSTITUTION: A partial shape of a permanent magnet or a whole shape of the permanent magnet is formed with a hemispheric body or a spheric body. A magnetizer of the permanent magnet has the inside and the outside which are formed with an N(S) pole and an S(N) pole, respectively. A partial shape of a shell of the permanent magnet or a whole shape of the shell of the permanent magnet is formed with the hemispheric body or the spheric body. The magnetizer of the permanent magnet has the inside and the outside which are formed with the N(S) pole and the S(N) pole, respectively.
