Automated Measurement of Levitation Force Using Labview Programming Language

This study deals with the development of an automated system for the investigation of levitation forces through three sets of experiments. The first set is a study of levitation forces between moving superconductors or conductors with a permanent magnet. The superconductors were used in field cooled...
