Abstract
A breakaway device for locking connected objects in relation to one another comprises a first magnetic field structure attached to a first object and a second magnetic field structure attached to a second object. The first magnetic field structure becoming attached to the second magnetic field structure when substantially aligned. The first structure and the second structure becoming detached when subjected to a force that overcomes a spatial force between the first magnetic field structure and the second magnetic field structure. The first magnetic field structure and the second magnetic field structure having magnetic field sources with polarities and positions in accordance with a code corresponding to a desired spatial force function.
