Abstract

This paper deals with the theoretical combination of magnetic forces, centrifugal forces, and gravity acting on low-χ magnetic fluids contained within a cylindrical shaped zone with a horizontal axis. The magnetic field is created by a combination of both quadrupolar winding and dipolar fields, as exists in superconducting coils developed for particle accelerators. Such a ground based device, if static, simulates a rotation – in space conditions – of a paramagnetic substance such as liquid oxygen. When the cylinder rotates, it creates exact gravity compensation – on Earth – for diamagnetic fluids such as hydrogen. These results go beyond a previous result that found it impossible to reach perfect magnetic compensation of gravity in a 3D domain.
