Can superconductivity contribute to the determination of the absolute ampere?

Abstract

The absolute ampere is shown to be derivable from a static levitation of a superconducting mass. The magnetic force which balances the gravitational force can be obtained from a combination of inductance and linear position measurements. A unique feature of the concept is the use of the calculable capacitor for the inductance measurements. Besides the possibility of this specific approach other concepts involving superconductivity are also discussed.
