The procedure for emitting / receiving of EM oscillations was discovered
by Michael Faraday
and called electromagnetic induction. Faraday noted that when current
is coupled to a primary coil, current is generated in another secondary
coil, concentric and galvanically separated.
On decoupling, the sense of the current generated in the secondary coil
It was the first device send / receiving EM oscillations between two coils
The induction phenomenon was then "translated" by James Clerk
Maxwell into a mathematical format.
Maxwell's equations have become a source of inspiration for using this
The idea of radio waves was later interfered with noise in telephone circuits
during elective discharges in the atmosphere. So lightning, arc, it was
emitting radio waves.
Heinrich Rudolf Hertz succeed experimentally to transmit an electrical
arc from the primary coil
to a resonant circuit (secondary coil) placed further.
Jagadish Chandra Bose covers the resonant circuit with gunpowder
and kindle it from 23m away.
It was the first remote!
The essence of the emission phenomenon however, has remained unknown until
How emit EM oscillations the lightning, electric arc?
In lightning existing no "electric current", of electric tasks,
of electrons or ions,
