How radio wave works: The mechanism of radio wave transmission by a transmitter antennae

How a radio wave really works?

Light is not electromagnetic wave, Maxwell’s theory is wrong

Introduction

Maxwell’s electromagnetic wave theory of light originated mostly from three phenomenons.1) When a conductor brakes a magnetic field, an electric field is created within the conductor, 2) Flowing of electrons through a conductor creates a magnetic field around that conductor, 3) Faraday effect- a magneto-optical phenomenon (the rotation of the plane of polarization by the application of a magnetic field). Maxwell has mistakenly concluded that, if an oscillating magnetic field creates an electric field in a conductor, an oscillating magnetic field will create electric field in empty space also. He has also believed that, oscillating electric field creates magnetic field. He has hurried with these observations and applied this in the development of his theory of light. The theory says that, light is an electromagnetic phenomenon and the perpendicularly oscillating electric and magnetic fields in space make the propagation of light.

In this article we can see that, an oscillating magnetic field can create an electric field only in a conductor and not in empty space.

When a conductor breaks a magnetic field, the magnetic field lines exert force on the free electrons in the conductor and which causes an unbalanced charges within the conductor. On the other hand, magnetic field is created when charged particles are aligned in a single mode in a material. [ "electric field and magnetic field will be created only in the presence charged particles, an electron has electric and magnetic field in right angle regardless of any kind of its motions and act as a tiny bar magnet with a negative charge.".]

Electric field

Electric field will be created in the below stated circumstances.

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

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

*Electric field lines hold nucleus and electrons in an atom 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).

Magnetic field

A charged particle (positive/negative) has magnetic property and act as a small magnet.When charged particles are aligned in a single mode in a material, a magnetic field will be created around that material. For example, when electrons are flowing through a conductor, all electrons will be aligned in a single way. This alignment of flowing electrons create a magnetic field around that conductor (flowing electrons cause to align them, otherwise, there is no any direct connections between motion of electrons and magnetic field). In a permanent magnet, outer electrons of the atoms of domains are aligned in a single way and all domains are also aligned in a single way. This alignment creates a magnetic field around a permanent magnet. In the case of an iron core inside of a solenoid, the influence of the magnetic field that created by the flowing electrons in the conductor, the outer electrons of the atoms of the iron core will be aligned in a single way and causes to create a magnetic field around the core.

Bending of magnetic lines: Mutual repulsion between the magnetic lines cause to bend them.

Charged particle

* Electron is a particle with having 'north pole dominated' magnetic property (electron's magnetic line starts from its north pole and ends at south pole).

* Proton is a particle with having 'south pole dominated' magnetic property.

* Negative charged particles (electron, antiproton etc) have north pole dominated magnetic polarity and positive charged particles (proton, positron etc) have south pole dominated magnetic polarity.

Flow of electrons through a conductor

We see above that, when electrons are flowing through a conductor, all electrons will be aligned in a single way and that alignment creates a magnetic field around that conductor. A low voltage- high current makes a short range, concentrated magnetic field. But, a high voltage- low current electron flow makes a long range (wide spreading), diluted magnetic field.

In a high voltage -low current electron flow through a conductor, there are two factors that affect the resultant magnetic field.

a) The drift velocity increases with the increasing of the voltage. b) As the current decreases, the number of magnetic field lines are created by the electrons will be less.

These two factors cause, the mutual repulsion between the magnetic lines to decrease because of the 'field density' at any point of the conductor is less, and which causes the magnetic field lines to spread at a wide range.

Oscillating magnetic field created by a radio wave transmitter

We can see that, the transmission range of a transmitter circuit sharply jumps when we deliver the signal to the circuit in the tuned frequency with an increased voltage.

The tuned frequency with the increased voltage influences the transmission range in two ways.

1) The circuit creates oscillating magnetic field lines with the minimum mutual repulsion between them because of the field density is minimum at any point (at resonance, voltage will be maximum and current will be minimum in the tuned circuit). In the minimum mutual repulsion, the magnetic field lines will be comparatively straighter and spread wide range.

2) Since the increased drift velocities at higher voltages, when the electrons oscillate, high amplitude oscillating magnetic field lines are created.

(Since the amplitudes of photons that emitted by atoms are almost the same for all frequencies, we consider only the photon’s frequency when we calculate its energy. But, the radio waves can be generated with different levels of amplitudes, they should be also considered along with the frequency, when we are calculating the energy of a radio wave photon).

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, a tiny electric potential is created in the antenna and a tuned receiver circuit can pick up the signal.
