Lift
Magnetic materials and systems are able to attract or press each other apart or together with a force dependent on the magnetic field and the area of the magnets, and a magnetic pressure can then be defined.
The magnetic pressure of a magnetic field on a superconductor can be calculated by:
where is the force per unit area in pascals, is the magnetic field just above the superconductor in teslas, and = 4π×10−7 N·A−2 is the permeability of the vacuum.
