Magnetic levitation assembly
First Claim
1. An apparatus for carrying a load, the apparatus comprising:
- a first structure spaced apart horizontally from a first side of a magnetizable structure and configured to generate magnetic flux;
a second structure spaced apart horizontally from a second side of the magnetizable structure and configured to generate magnetic flux, wherein the second side is opposite the first side, and wherein the first and second structures are magnetically attracted to the magnetizable structure;
a third structure spaced apart vertically from the magnetizable structure and configured to generate magnetic flux, wherein the third structure comprises an upper portion and a lower portion of opposite polarities and wherein the lower portion is positioned to magnetically repel from an upper portion of the magnetizable structure; and
a flux guide positioned between an inner surface of at least one of the first and second structures and an outer surface of the third structure, wherein the flux guide comprises a magnetizable material.

Abstract
A method and system for transportation using a magnetic bearing structure is disclosed. In one aspect, there is an apparatus for carrying a load along a magnetizable structure. In one embodiment, the apparatus comprises a third structure spaced apart vertically from the magnetizable structure and configured to generate magnetic flux and repel from the magnetizable structure. In one embodiment, the apparatus comprises at least one coil positioned at at least one end portion proximal to the magnetizable structure. In one embodiment, the apparatus comprises at least one flux guide comprising a magnetizable material and configured to concentrate magnetic flux. A first portion of the flux guide is thinner than a second portion of the flux guide that is positioned closer to the magnetizable structure than the first portion of the flux guide.
