Abstract

Magnetic levitation experiments of some diamagnetic materials in high magnetic fields have been done by using a hybrid magnet of Tohoku University. Water located near the edge of the water-cooled magnet, for example, becomes a globe and levitates when a field at the center of the magnet is above 20.5 T. As the first application of water levitation, we tried to make an ice crystal at the levitating condition and it turned out that the crystallization process shows complicated and strange behavior at supercooled -10°C. Synthesis of a dendrite ice crystal was also tried and it was first found that the directions of growing branches are different. But this effect seems to be not due to the levitation effect but due to the orientation effect.
