Cathode
tube vectorially interpreted.
The cathode tube is the device that converts EM oscillations into optical
images.
The cathode, control grid and fluorescent screen are the essential elements.
The cathode incandescent gives atoms the freedom to orient the EM polarities.
At circuit closure, EM force aligns its orthogonal polarities, as Oersted
discovered in 1820,
and forms a dynamic equilibrium medium to propagate EM oscillations.
Behold and the answer to the questions expected 200 years, why and how
the magnetic field appears.
In the grid, EM information it compound with centripetal force and results
in a dynamically modulated balance (the variable oriented polarities density).
The deflection coils command the magnetic component of the force EM and
the direction of the electrical polarities. Electrical polarities focused
on the fluorescent layer atoms, cause optical radiation.
All EM interactions are transverse on the direction of electrical polarities
