Force Density of Magnetic Bearings Using Superconducting Coils and Bulk Superconductors

Last updated on 04 January 2013 5:42

Stable levitation or suspension of a heavy object in mid-air can be realized using a combination of a permanent magnet and a bulk superconductor with high critical current density, in that the force density has reached 100 kN/m2. The superconducting flywheel system for energy storage is attractive due to a...
