Abstract

An improved system and method for moving an object includes a first correlated magnetic structure associated with a first object and a second correlated magnetic structure associated with a second object. The first and second correlated magnetic structures are complementary coded to achieve a peak attractive tensile force and a peak shear force when their code modulos are aligned thereby enabling magnetic attachment of the two objects whereby movement of one object causes movement of the other object as if the two objects were one object. Applying an amount of torque to one correlated magnetic structures greater than a torque threshold causes misalignment and decorrelation of the code modulos enabling detachment of the two objects. The number, location, and coding of the correlated magnetic structures can be selected to achieve specific torque characteristics, tensile force characteristics, and shear force characteristics.
