Abstract
A multilevel magnetic system described herein includes first and second magnetic structures that produce a net force that transitions from an attract force to a repel force as a separation distance between the first and second magnetic structures increases. The multi-level magnetic system is configured to maintain a minimum separation distance between a transition distance where the net force is zero and a separation distance at which a peak repel force is produced.
Claims20
A magnetic system, comprising:
- a first magnetic structure;
- a second magnetic structure;
- and
- at least one movement constraining structure that limits movement of said first magnetic structure relative to said second magnetic structure to a plurality of alignment positions, said plurality of alignment positions including a first alignment position where said first and second magnetic structures produce a first composite force curve where a net force transitions from an attractive force to a repel force as a function of the separation distance between said first and second magnetic structures, said plurality of alignment positions including a second alignment position where said first and second magnetic structures produce a second composite force curve where a net force does not transition from an attractive force to a repel force as a function of the separation distance between said first and second magnetic structures.

A magnetic system, comprising:
- a first magnetic structure;
- and
- a second magnetic structure, said first and second magnetic structures producing a first composite force curve where a net force transitions from an attractive force to a repel force as a function of the separation distance between said first and second magnetic structures when said first magnetic structure is in a first alignment position relative to said second magnetic structure, said first and second magnetic structures producing a second composite force curve where a net force does not transition from an attractive force to a repel force as a function of the separation distance between said first and second magnetic structures when said first magnetic structure is in a second alignment position relative to said second magnetic structure.
