  • Abstract
    This paper examines the "magnetic potential well" effect by the example of two ring-shaped superconductive coils. This effect allows us to create a noncontact magnetic suspension of one coil and to define its movements by measuring the current in the stationary coil. It is shown that the system of these two coils is unstable with respect to the tilt angle. The new construction of the levitated coil, which allows us to create the completely stable suspension is examined. The solution of the equation of test mass motion and the acceleration-to-current transfer function for low-frequency acceleration are found. The other type of superconducting accelerometer is briefly described for comparison.
