1. A magnetic system comprising:
a first multi-pole magnet comprising a first plurality of polarity regions having a first polarity pattern; a second multi-pole magnet comprising a second plurality of polarity regions having a second polarity pattern; a third multi-pole magnet comprising a third plurality of polarity regions having a third polarity pattern; and a fourth multi-pole magnet comprising a fourth plurality of polarity regions having a fourth polarity pattern; wherein when said first polarity pattern is aligned with said second polarity pattern, said first multi-pole magnet and second multi-pole magnet produce a first composite force curve, said first composite force curve comprising a first force curve with a first extinction rate and a second force curve with a second extinction rate, wherein said first composite force curve is an attract force curve and said first force curve is an attract force curve and said second force curve is a repel force curve and said first extinction rate is greater than said second extinction rate, wherein the first magnetizable material is moveable relative to said second magnetizable material in at least two dimensions for a first portion of said first composite force curve, wherein said first multi-pole magnet is moveable relative to said second multi-pole magnet in only one dimension for a second portion of said first composite force curve, wherein said first multi-pole magnet and said second multi-pole magnet have a direction of magnetization, and wherein said first multi-pole magnet is moveable to said second multi-pole magnet substantially parallel to the direction of magnetization, wherein when said third polarity pattern is aligned with said fourth polarity pattern, said third multi-pole magnet and said fourth multi-pole magnet produce a third magnetic force curve and a fourth magnetic force curve, said third and fourth magnetic force curves combining to produce a second composite force curve, wherein said first and third multi-pole magnets are attached to a first object in a first straight line with a spacing between said first and third multi-pole magnets, and wherein said second and fourth multi-pole magnets are attached to a second object in a second straight line with a spacing between said second and fourth multi-pole magnets, and wherein when said first object and said second object are aligned such that said first straight line is substantially parallel to said second straight line, said first composite force curve and said second composite force curve combining to produce a third composite force curve. |
