Method and apparatus for magnetic levitation

Abstract

A method to maintain magnetic levitation that is stabilized by means of Hall effect sensors is disclosed. The method and device comprising a Hall effect sensor or sensors used to control an electromagnet to maintain the position between two magnets or objects. The present invention has been used to suspend a magnet in a high pressure tube that is magnetically coupled to a magnet outside the tube connected to an analytical balance that can accurately measure the force on the magnet inside the tube. This force measurement can be used to determine fluid density, flow, viscosity, and solubility. This magnetic levitation method also has application for other devices such as motors, generators, trains, turbines, wind tunnels, and entertainment devices.
