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 The superconducting disc in this case has been replaced by a diamagnetic copper cylinder.

I've come across another excellent amateur radio book from 1922 . The book details all manner of circuits and apparatus including the variometer shown to the left. The variometer was a couple inductance device that worked by rotating one 'honeycomb' coil within another. When the coils were at right angles, very little coupling resulted and when they shared a parallel winding axis, the greatest inductive coupling was obtained. The book also contains an inspiring discussion of the value of amateur radio to students. It's excerpted in the two pages below:

In his 1992 Physica C paper, Podkletnov references the use of a toroidal solenoid as the levitation coil for the superconducting disc. In Hathaway's 2003 reported replication attempt, he describes the same coils as pancake coils. It was unclear to me if a toroidal solenoid and a pancake coil were in fact the same device. It turns out that they are in fact different names for the same thing. See the page excerpted from the "Standard Tables and Equations in Radio-Telegraphy" by Bertram Hoyle, (1919), below.

Here's a suggestion for how the threaded two rotation coil version of Podkletnov's apparatus works. A diagram of the coil arrangement is shown below. Only one of the coils is shown in the diagram. The second coil is a mirror image of the first on the right side of the disc. From EE Podkletnov, arxiv, (1997), http://arxiv.org/abs/cond-mat/9701074 The magnetic field, (B coil), created by the coil will be parallel to the surface of the superconducting disc. Via the Meissner effect, supercurrents will be setup in the superconductor that are parallel to the coil windings, but in the opposite direction. These supercurrents are at right angles to the magnetic field that originally created them. The magnetic field, (B supercurrent), setup by the supercurrents opposes the magnetic field in the rotation coil, (see figure below). If the two rotation coils are driven by alternating currents that are 180 degrees out of phase, then the opposing magnetic fields setup by the superc...

While searching for information on pancake coils for the New Mexico State University Superconductor Gravity experiment, I came across a great book: "High frequency apparatus: its construction and practical application' by Thomas Stanley Curtis The book was published in 1916 and contains a great deal of detail on how to construct Tesla coils and other high frequency, and typically high voltage apparatus. Nothing is left out of the instructions. Among other things, the book even details how to make your own capacitor from glass plates.

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:

The Podkletnov apparatus we're reconstructing in the New Mexico State University Superconductoro Gravity experiment places a superconducting disc in two orthogonal oscillating magnetic fields. Early nuclear magnetic resonance experiments by Bloch and Purcell's groups used a constant magnetic field in combination with an orthogonally oriented RF coil that was driven around 29 MHz, (a frequency in the same range as that used by Podkletnov for the rotation coils). Li and Torr, two of the early researchers of the Podkletnov effect hypothesized that gravitomagnetic fields might be observed as the result of aligned nuclear spins in superconductors.
