ABSTRACT:
A magnetic guidance and support system and method. The magnetic system comprises a core member and a central member. The core member includes an interior surface forming an interior, and also forms an opening in communications with that interior. The central member of the system includes an electrically conductive cylinder positioned in the interior of the core member, and connecting means connected to the cylinder and extending outward therefrom and through the opening in the core member. The magnetic system further comprises a multitude of electrical conductors axially extending along and annularly spaced around the core member, and an electric power supply connected to the electrical conductors to conduct an electric current through those conductors. When this current is conducted through the electric conductors, the conductors produce a magnetic quadrupole having a magnetic field for supporting the cylinders in the interior of the core member and spaced from the interior surface thereof.
