FIG. 1 shows an example of a cylindrical magnet as an example of a permanent magnet whose magnetization direction is convergent. The arrow indicates the magnetization direction of the magnet cross section. FIG. 2 shows the magnetic flux density distribution on a parallel plane relatively close to the magnetic pole surface of a permanent magnet whose magnetization direction is straight. Specifically, A shows the shape of the permanent magnet and the parallel plane A-A' for measuring magnetic flux density, and B shows its surface magnetic flux density distribution. FIG. 3 shows the magnetic flux density distribution on a parallel plane relatively far from the magnetic pole face of a permanent magnet whose magnetization direction is straight. Specifically, A shows the shape of the permanent magnet and the parallel plane B-B' for measuring magnetic flux density,
Figure A shows the surface magnetic flux density distribution. FIG. 4 shows an example of the surface magnetic flux density distribution of a permanent magnet whose magnetization direction is straight. Specifically, Figure A shows the shape and dimensions of the permanent magnet and the parallel planes C-C' and D-D' for measuring the magnetic flux density of both magnetic pole faces, and Figure 2 shows the surface magnetic flux density distribution. FIG. 5 shows an example of the surface magnetic flux density distribution of a permanent magnet whose magnetization direction is radial. Specifically, (a) the shape and dimensions of the permanent magnet and the measurement of the magnetic flux density of both magnetic pole faces on parallel planes E-E', F-F;
' is shown, and A shows its surface magnetic flux density distribution (to obtain a magnet with the magnetization direction shown in this figure, adjustment is made by the magnetic field during powder pressing).
