Method and system for transportation using a magnetic bearing structure
First Claim
1. An apparatus for carrying a load, the apparatus comprising:
- a source of magnetic flux comprising;
a first upper portion and a first lower portion of opposite polarities, wherein the first portions are spaced apart horizontally from a first side of a magnetizable structure; and
a second upper portion and a second lower portion of opposite polarities, wherein the second portions are spaced apart horizontally from a second side of the magnetizable structure, wherein the second side is opposite the first side, and wherein the first and second upper portions are magnetically attracted to an upper portion of the magnetizable structure and the first and second lower portions are magnetically attracted to a lower portion of the magnetizable structure;
an inner flux guide attached to an inner surface of the source of magnetic flux;
an outer flux guide attached to an outer surface of the source of magnetic flux, wherein the inner and outer flux guides comprise a magnetizable material; and
a controller configured to control the position of the source of magnetic flux relative to the magnetizable structure.

Abstract
A method and system for transportation using a magnetic bearing structure is disclosed. In one aspect, an apparatus for carrying a load comprises a source of magnetic flux and a controller configured to control the position of the source of magnetic flux relative to a magnetizable structure. The source of magnetic flux comprises a first upper portion and a first lower portion of opposite polarities. The first portions are spaced apart horizontally from a first side of the magnetizable structure. The source of magnetic flux further comprises a second upper portion and a second lower portion of opposite polarities. The second portions are spaced apart horizontally from a second side of the magnetizable structure. The second side is opposite the first side. The first and second upper portions are magnetically attracted to an upper portion of the magnetizable structure and the first and second lower portions are magnetically attracted to a lower portion of the magnetizable structure.
