Electric field, magnetic field and how is radio wave created?

Watch videos: What is radio wave? and What is Light?

"Electric field and magnetic field, both are created only in the presence of charged particles. Oscillation of one field (electric/magnetic) in empty space creates no other field as current belief. So, Maxwell’s electromagnetic wave theory of light is wrong.".

Electric field and magnetic field:

Charged particle like electron has a standing-electric field and magnetic field in right angle regardless of any kind of its motions (evidences for the right angle relationship). Watch video: Structure of electron (http://www.youtube.com/watch?v=HWGa3lkTFP8)

Electric field will be created in the below stated circumstances:

a) A charged particle (negative/positive) creates an electric field around that particle.

b) An oscillating magnetic field creates an oscillating electric field within a conductor.

*Electric field lines hold nucleus and electrons in an atom are together; atoms in a molecule are together.

*An unbalanced and opposite charges within a conductor or between two conductors cause the flow of charges through that conductor (s).

Because of the mutual repulsions, the electric field lines created by a charged body will be always are bended.

Magnetic field will be created in the below stated circumstances:

a) A charged particle like electron acts as a ‘tiny’ magnet. When electrons are flowing through a conductor, they will be aligned. This alignment of flowing electrons creates a collective magnetic field around that conductor. Flowing of electrons cause to align them; otherwise there is NO any direct connection between electric current and magnetic field.

b) In the case of an iron core inside of a solenoid, by the influence of the magnetic field that created by the solenoid, the outer electrons of the atoms of the iron are aligned in a single way and creates a magnetic field.

c) In a permanent magnet, the outer electrons of the atoms of the domains are aligned in a single way and all domains are also aligned in a single way creates its magnetic field (Watch video: Magnetic field http://www.youtube.com/watch?v=CYO-JV_Tn3U )

* A magnetic field created by a body can stretch vast areas. For example, the magnetic field created by celestial objects likes the Earth, Sun etc. 

*A Magnetic field line has the ability to physically influence on charged particles. For example, the influences of oscillating magnetic field on the electrons in an induction coil, in the coils of electric generator or transformer etc. Also, the influence of oml photons (intermittent oscillating magnetic lines) with the sufficient frequency, when they fall on some elements causes the photoelectric effect.  

Oscillating magnetic field created by a radio wave transmitter (how is radio wave created?)

The flow of electrons through a conductor is caused by the attraction between electric fields of “mobile” electrons and the “fixed” positive charges in the conductor. I.e. the electrons move to the direction of positive charge. The oscillation of electrons in a conductor (radio wave transmitter) is caused by the alternation in the direction of attraction on electrons. Since the electron has electric and magnetic field in right angle, when electrons oscillate in a conductor, the oscillating magnetic lines created by the electrons is radiated to space perpendicular to their oscillations. As the drift velocity increases with the increasing of voltage, when electrons oscillate at higher voltages, a radio transmitter creates high amplitude oscillating magnetic lines.

Induction in the receiver antenna

We see above that, an oscillating magnetic field creates an oscillating electric field in a conductor. When the oscillating magnetic lines fall on the receiver antenna, just like the electromagnetic induction in a dynamo or a transformer, tiny oscillating electricity is created within the antenna and a tuned receiver circuit can pick up the transmitted signal.

Why do radio waves are bending and light is not?

Bending of magnetic lines is caused by the mutual repulsion between them. As the length of oscillating magnetic lines increases, the chances of mutual repulsion between them will be also increased (radio wave to microwave) and they bend significantly. But short wavelength photons make minimum mutual repulsions between them and they travel almost straightly.

"Since the photon (intermittent) nature of light, it is very difficult to influence on light by magnetic field. But a continues radio wave transmitted by a simple radio wave transmitter, can be disturbed with the help of a strong magnetic field".
