Characteristic Analysis of a AC Superconductig Coil moving above a conducting slab

도체판 위를 운동하는 교류용 초전도자석의 특성해석

This paper investigates the force on a rectangular AC supercoducting coil moving above and parallel to a conducting plate of finite thickness. Expressions are developed for the levitation and drag forces on the coil a a function of speed and frequency. The levitation force are generated at all speed including stand still in a AC supercoducting coil. The levitation and drag forces on a rectangular AC supercoducting coil are compared with those on a rectangular DC supercoducting coil moving above and parallel to a conducting plate.
