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.

Famous quotes containing the word lift:
“When will the veil be lifted that casts so black a night over the universe? God of Israel, lift at last the gloom: For how long will you be hidden?”
—Jean Racine (1639–1699)
“Conventionality is not morality. Self-righteousness is not religion. To attack the first is not to assail the last. To pluck the mask from the face of the Pharisee is not to lift an impious hand to the Crown of Thorns.”
—Charlotte Brontë (1816–1855)
“Men, forever tempted to lift the veil of the future—with the aid of computers or horoscopes or the intestines of sacrificial animals—have a worse record to show in these “sciences” than in almost any scientific endeavor.”
—Hannah Arendt (1906–1975)
