Enhancement of Levitation Force Characteristics in High Tc Superconducting Levitation.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1996 Two methods for superconducting magnetic levitation are investigated to enhance levitation characteristics such as levitation force and horizontal stability. In one of the investigated methods, not only a repulsive force between a permanent magnet and a superconductor but also the force between two permanent magnets is utilized to achieve strong ...

Non-additivity of magnetic levitation force
Journal of Physics: Conference Series, 2006 We present results of experimental measurements and numerical simulations of influence of superconductive block thickness on value of magnetic levitation force. It was found that dependency of magnetic levitation force on thickness of superconductive block is nonlinear both ZFC and FC conditions that means a non-additivity of levitation force.
