Seibt Coils

Seibt Coils

The Seibt-Coil was invented and published by Dr. Georg Seibt, a radio-pioneer and -company owner, in his PhD-thesis, which might reside in some German university library: "Rostocker-Inaugural-Dissertation 1902", also in "Elektrotechnische Zeitschrift 1902, Heft 15-19". The only purpose of it is: to demonstrate / visualize the existence of standing electromagnetic waves, along a resonator coil., resonant in different overtones above the fundamantal quarterwave frequency. The basic way, this demonstration is visualized, by means of corona-zones developping along the coil, contributes to the fascination of the experiment. As an alternative to the corona-zone display, a long vacuum tube can be installed along the coil, leading to a brighter display, than the faint glowing corona.
