Lorentz transformation of toroid polarization

Characteristics of and Control over Resonance in the Electromotive Force of Electromagnetic Induction

“…If the phase difference arose from the acceleration of conducting electrons induced by the electromagnetic radiation (generated from the source coil), the phase difference may be effectively independent of A f at high frequencies. However, if the phase difference arose from the oscillations in the electric/magnetic dipoles or toroidal dipoles 1 [8][9][10][11][12][13][14] induced by the electromagnetic radiation, the phase difference would be expected to depend on A f at high frequencies. The radiation resistance in a coil with turns composed of an electrically conductive copper wire may be modeled as follows.…”

“…The toroidal dipole moment represents the lowest moment of the third independent electromagnetic multipole family, after the electric and magnetic moments. The properties of materials that possess toroidal moments and the classification of their interaction with external electromagnetic fields are topics of growing interest [8][9][10][11][12][13][14]. anti-resonance frequency AR f could be adjusted, we examined the influence of three experimental parameters on the R f and AR f .…”
