Comment: Superconductor and Anti-magnetism (Score 2, Interesting) 430

by Varragon (#3221253) Attached to: NASA Still Trying to Verify Anti-Gravity Claims
Superconductors possess a very interesting phenomena. They are anti-magnetic. Several years ago I attended a physics day at a local university. In one of the exhibits a grad student was demonstrating this property. He place a small magnet on a superconductor and poured liquid nitrogen on the superconductor. The magnet rose and floated about an inch above the superconductor. I asked the grad student what would happen if he repeated the demostration and placed a supermagnet (a rare earth magnet) ontop the superconductor. He said he was game. We stole a supermagnet from another demostration and conducted the experiment. When the liquid nitrogen was poured on the superconductor, the supermagnet shot up in the air like a bullet, ricocheted off the ceiling and rattled around the room. The antimagnetic property of a superconductor is not polarity oriented. The effect will work no matter which pole is placed ontop the superconductor. It is a repulsive force not an attractive force.
Since superconductors already possess one unique attribute (anti-magnetism), it would be very intriguing if it might possess a second (anti-gravitiationl). The other passing thought is that the world has longed for an anti-gravitational engine, but maybe it was right in front of our noses all the time but it was called something else, an anti-magnetic engine. The Earth along with many planets and stars in the universe possess magnetic fields.

Money will say more in one moment than the most eloquent lover can in years.
