Confinement of KOe Magnetic Fields to Very Small Areas in Miniature Devices.
Abstract
This patent application discloses a rare earth permanent magnetic apparatus for the containment and control without any substantial loss of field flux comprising electro-deposited layers of rare earth magnetic material disposed and laid up around a ferrite center core element, the first or inner layer comprising a uniformly thick supply magnet to produce the magnetic field to be controlled, and the second or cladding magnet constituting a layer of diminishing thickness from the outboard ends of the device towards and to the plane of zero magnetic potential at or near the middle of the device.
