Patent ID: 8643454

Claim:
A magnetic system, comprising: a first magnetic structure comprising a first plurality of magnetic field sources having a first polarity pattern; and a second magnetic structure comprising a second plurality of magnetic field sources having a second polarity pattern, said first magnetic structure and said second magnetic structure producing a peak spatial force when said first magnetic structure is in an aligned position with said second magnetic structure where said first polarity pattern is aligned with said second polarity pattern, said first magnetic structure and said second magnetic structure producing a plurality of off peak spatial forces including a plurality of release forces when said first magnetic structure and said second magnetic structure are in a corresponding plurality of misaligned positions where said first polarity pattern is misaligned with said second polarity pattern, each release force of said plurality of release forces resulting from the combined magnetic field sources of said first magnetic structure and said second magnetic structure cancelling each other to some extent causing the overall field strength of the combined magnetic field sources to be substantially dampened, wherein said first magnetic structure and said second magnetic structure each comprise N magnetic field source areas having substantially the same size and the ratio of the magnitude of the peak spatial force to the magnitude of the maximum off peak spatial force is substantially N.
