This chart shows the manufacturing process of magnets from the
Ningbo Yili Magnetic Co. in China.
Magnet Types:
There are
Isotropic Magnets; where magnetic properties are equal
in all directions. There are
Anisotropic Magnets which have a
preferred direction of magnetic orientation where its magnetic
characteristics are optimum in one preferred direction also
called
unipole or unidirectional.
Our beads are unidirectional,
producing fields flowing only from the north to the south
providing your body with maximum therapeutic benefits.
Unidirectional magnets are most effective in increasing
circulation and oxygen levels.
Production
Ferrites are produced by heating a mixture of powdered precursors
pressed into a mold where calcination occurs. This mixture of oxides
undergoes sintering or high temperature firing. The cooled product is
milled into tiny particles of powder which is pressed into a shape,
dried and re-sintered inside an external magnetic field to achieve a
preferred orientation [anisotropy]. Lower grade include dry pressing,
direct calcination and sintering without re-milling leading to poor
magnetic properties. We only use the highest quality magnetic beads.
