Hysteretic levitation forces in superconducting ceramics
Applied Physics Letters, 1988Magnetization forces between small permanent magnets and bulk high Tc superconducting ceramic materials have been measured and show marked hysteretic behavior as a function of the distance between the magnet and superconductor. Magnetic forces of up to 2500 dyn, both normal and tangential to the superconductor surface, have been made.

Magnetic levitation force of composite magnets in a ferrofluid damper
Smart materials and structures (Print), 2018Larger radical levitation force is favorable for enhancing energy dissipation in ferrofluid dampers. Utilization of composite magnet structures is one of the candidate methods to increase this force.

Optimizing levitation force and stability in superconducting levitation with translational symmetry
Applied Physics Letters, 2007From a theoretical analysis based on an energy minimization procedure and the critical-state model, the authors analyze the levitation of an infinitely long superconductor above infinitely long permanent magnets with different arrangements. A discussion on optimum geometries showing large levitation force and good stability is presented from the model ...

Numerical simulation of levitation force and magnetic field in levitated bulk superconductor
Physica C: Superconductivity, 2004It is known that the levitation of bulk superconductors could successfully be controlled using a Bi2223 superconducting electromagnet. In the previous study, we directly measured the levitation force and magnetic field on the surface of bulk superconductors levitated by this electromagnet.

Verification of levitation force between an HTS levitator and a permanent magnet
Physica C: Superconductivity, 2007Abstract The levitation force between a high-temperature superconducting (HTS) levitator and a permanent magnet has been analyzed, and different theoretical models can be applied which have different J c – B relationships. Characteristics like magnetization and levitation force are strongly dependent on the J c – B relations, the way to obtain ...
