ABSTRACT:
A method and apparatus for establishing the magnetic permeability of a batch ferrites at a predetermined target permeability. Ferrite parts are sintered to achieve a magnetic permeability greater than the target permeability. The sintered parts are then tumbled to suppress the magnetic permeability below the target permeability. The parts are then exposed to a chemical wash to increase the magnetic permeability and continuously monitored to allow setting the magnetic permeability at the target permeability.
