Abstract: A set of holding magnets is provided that exhibit shaped edges or surfaces that provide some extra mechanical strength to aid in improving upon the shear force resistance capabilities while in a holding relationship. In one embodiment, the longitudinal edge of one magnet is notched (or grooved) while its mating magnet exhibits a protrusion along one of its longitudinal edges. When the magnets are brought together so that the protrusion is inserted at least part-way into the notch, the two magnets will hold together using both magnetic and mechanical properties to advantage. The holding relationship will exhibit an increased shear force resistance that otherwise would entirely depend upon the magnetic strength to prevent a shear force from pulling the two magnets apart. In a second embodiment, the planar top surface of one rectangular strip magnet is notched (or grooved) while its mating magnet exhibits a protrusion along one of its rectangular surfaces.
