Anisotropic magnets, in contrast to isotropic magnets, do not have the same levels of magnetism in all spatial planes. Instead, they feature a preferred direction of magnetization.

Anisotropic magnets are pressed or injection moulded in the presence of a magnetic field, and all grains are thereby rotated into the future direction of magnetisation. They have very good magnetic properties in their preferred direction, and attain nearly double the magnetic flux of isotropic magnets.

However, it is not possible to magnetise anisotropic magnets perpendicular to their preferred direction.

Mainly, they are ring and disc magnets with axial preferred direction and rectangular magnets with preferred direction along their height.

Magnets for special applications, such as motors or pumps, whose preferred direction is made perpendicular to the axis (diametrical).

Plastic bonded magnets whose grains are oriented to be multipolar (pole-oriented) via a magnetic system in the injection mould.
