At the Precession Circle research continues on finding ways to acquire usable electrical energy by conversion from the kinetic energy of elementary particles whose magnetic poles gyrate under an applied magnetic field.

The following list was compiled by S.H.O. talk 14:00, 5 August 2019 (PDT):

  • Burgner, R. & Renlund, G. (2008). "Electric Generator" Patent US20080246366A1
    "Methods, compositions, and apparatus for generating electricity are provided. Electricity is generated through the mechanisms nuclear magnetic spin and remnant polarization electric generation."
  • Hnizdo, V. & McDonald, K. (2015). "Fields and Moments of a Moving Electric Dipole"
    "....[math]\mathbf{E}_p[/math] and [math]\mathbf{E}_m[/math] can also be interpreted as the electric fields associated with the polarization and magnetization densities of the moving magnetic dipole, respectively."
  • Kholmetskii, A., Missevitch, O., & Yarman, T. (2012). "On Relativistic Polarization of a Rotating Magnetized Medium"
    "We show that the polarization of a magnet brought to a rotation differs, in general, from the relativistic polarization of a translationary moving magnet, and on this way we give one more explanation to the familiar Wilson & Wilson experiment, with the explicit demonstration of the implementation of the charge conservation law."
  • Kholmetskii, A., Missevitch, O., & Yarman, T. (2013). "Relativistic transformation of magnetic dipole moment"
    "In the present paper, we will show that the determination of correct relativistic transformation for magnetic dipole moment requires to carry out a careful analysis of parameters of compact bunches of charges and the notion of magnetic dipole moment itself, as seen in different inertial reference frames. This way we find the explanation for disagreement of Equations (10), (11) and obtain the general solution of the problem of transformation of magnetic dipole moment."
  • Silenko, A. (1991). "Current electric quadrupole moments of atoms and nuclei"
    "It is shown that current electric multipoles exist. Their field is electrostatic and it is unrelated to the existence of a net electric charge. At long range, it is the same as the field of the corresponding charge electric multipoles. Current electric multipoles arise during the motion of magnetic multipoles. An orbital motion of magnetic dipoles, a precession of a current-carrying loop, and the motion of magnetic quadrupoles all lead to current electric quadrupole moments. Expressions for the current electric quadrupole moments of atoms and nuclei are derived."
