NMSU Superconductor Gravity Experiment: Liquid Helium Fluid Drag Demo

One of the Podkletnov rotation magnetic field arrangements essentially 'points' a set of solenoid at the side of the superconducting disc. I came across a demonstration from the 1963 movie by Alfred Leitner about liquid helium that uses a very similar setup. The superconducting disc in this case has been replaced by a diamagnetic copper cylinder.

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. Apparatus Demonstration: MIT Tech TV Apparatus Explanation:

NMSU Superconductor Gravity Experiment: The Podkletnov Apparatus' Rotational Solenoids

One of the first tasks in this project has been to determine what the Podkletnov apparatus should do when it is operated and what physical mechanisms account for each aspect of the operation. In Dr. Podkletnov's papers, he points out that the disc is rotated with the use of solenoids that are placed around the superconducting disc in a number of configurations as shown below. I'll compare these configurations to other existing superconductor motor research in a future entry. From EE Podkletnov, arxiv, (1997), http://arxiv.org/abs/cond-mat/9701074 The above diagram shows the two phase coils that are wrapped through the disc. The magnetic field inside these solenoids will be parallel to the surface of the disc. The dashed circles indicate the levitation solenoids that lie below the disc. The next diagram is a detail of one of the through wrapped solenoids as well as a second solenoid configuration in which the solenoid windings are bent out of the way of the disc. To...
