A method of producing a material for permanent magnets, said method comprising mixing anisotropic particles, substantially of domain size, of a permanent magnet material with a non-magnetic matrix material capable of being worked, and kneading the resulting mixture between rollers to give an elongated shape, whereby the preferred magnetic axes of said particles are aligned substantially perpendicular to the surface of said elongated shape, said permanent magnet material being adapted to be magnetized to form an anisotropic permanent magnet by applying a field to said material magnetizing that is directed perpendicularly to the surface of said material.
