Abstract: An improved magnetic attachment system involves a female component that is associated with a first object and a male component that is associated with a second object. The female component includes a hole and a first magnetic structure having a first plurality of magnetic source regions having a first polarity pattern. The male component includes a peg that can be inserted into the hole and a second magnetic structure having a second plurality of magnetic source regions having a second polarity pattern complementary to said first polarity pattern. The male and female component are configured such that when the peg is inserted into the hole the first and second magnetic structures face each other across an interface boundary enabling magnetic attachment of the first object to the second object, where while the peg remains inserted within the hole the male component can be rotated relative to the female component but translational movement of the male component relative to the female component is constrained.

Abstract: An improved system for concentrating and controlling magnetic flux of a multi-pole magnetic structure at the surface of a ferromagnetic target uses first pole pieces having a magnet-to-pole piece interface with a first area and a pole piece-to-target interface with a second area substantially smaller than the first area for concentrating flux of the multi-pole magnetic structure at each pole piece-to-target interface, where the target can be a ferromagnetic material or complementary pole pieces.

Abstract: A shunt plate is provided that is associated with a first side of a multi-pole magnetic structure. The shunt plate provides a magnetic short between opposite polarity magnetic sources on the first side of said magnetic structure, the magnetic short causing a magnetic flux of said opposite polarity magnetic sources to be routed from said first side of the magnetic structure through said magnetic structure to the second side of said magnetic structure. The thickness of the shunt plate is selected by determining the integrated flux across a magnetic source of the magnetic structure such that the corresponding flux density in the shunt plate does not substantially exceed the flux density saturation level of a cross section of the shunt plate.
