ABSTRACT:
A magnetic folio or notebook, capable of handling up to 40 or more sheets of paper, includes two notebook covers which are hingedly secured together, with a thin strip of permanent magnet material secured to one of the covers near the binding of the notebook. A second thin strip of magnetic material is mounted either on the other cover of the folio or notebook, or on a thin strip of flexible material, so that it may fold over on top of the first permanent magnet strip to hold a stack of papers between the two strips. The permanent magnet strips may be formed of ferrite material, with successive north and south poles along the length of the magnet strips from the top to the bottom of the notebook. The two mating magnet strips will have a corresponding pattern of magnet poles along their lengths, but with the north magnetization for one strip matching the south magnetization areas on the other strip, and similarly with the south magnetized areas of polarization of one strip matching the north pole areas of the other strip. Thin strips of magnetic material, such as cold-rolled steel, may extend along the back side of each of the permanently magnetized strips in order to enhance the holding properties of the opposed permanent magnet strips. Suitable adhesives may be employed to hold the magnet strips, the magnetic material, and the notebook or folio assemblies, together.
