NMSU Superconductor Gravity Experiment: Superconductor as Induction Motor Rotor

One of the interesting aspects of the project so far has been determining how to model the rotation of the superconducting disc in the Podkletnov apparatus. The variety of rotation coils described by Podkletnov has made the task somewhat more difficult. One of the early thoughts was that the superconductor rotated due to eddy currents created by the two-phase magnetic fields created by the rotation coils. The first video below shows a similar rotation of a normal conducting 'egg' in the presence of a rotating magnetic field created by a three-phase toroid. The next video explains the physics behind the apparatus around the time 23:35.
