  • Floating/melting using dummy micro-gravitational field by magnetic force
    Patent number: 6452140
    Abstract: A substance 6 is located in a gradient magnetic field and held in a levitating state by a magnetic force produced by the gradient magnetic field. The substance 6 as such in the levitating state is heated and melted by ray or heat irradiation or by a resistance heater. Thereafter, the heating is stopped, and the substance 6 is cooled as such in the levitating state. Since the magnetic force realizes the microgravity field where the substance 6 is melted and cooled in the levitating state, the substance 6 is formed to an ideally spherical shape with an extremely smooth surface.
