Explain the basic principle of working of radio?

Radio is the transmission of signals, by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.


What are the rays in the cathode ray tubepositive or negative or neutral?

The rays produced in a cathode tube in early experiments were actually just streams of electrons. They had a negative charge, which was discovered by JJ Thomson when he placed a magnet next to his cathode ray tube and say the ray bend.


Which scientist used the cathode ray tube to isolate the electron in 1897?

J.J. Thomson used the cathode ray. Thomson's cathode ray experiment was when he shot a narrow beam of electrons through a cylindrical tube and deflected the electrons off of electric and magnetic fields, thus measuring the effects that those fields had on the direction of the beam.


How many ways are there to generate an emf?

Electromotive force (emf) can be generated in several ways, primarily through electromagnetic induction, chemical reactions in batteries, and thermoelectric effects. In electromagnetic induction, emf is generated by changing magnetic fields or relative motion between a conductor and a magnetic field. Batteries produce emf through electrochemical reactions, while thermoelectric generators convert temperature differences directly into electrical energy. Each method utilizes different principles of physics and chemistry to generate electrical energy.


How does mobius coil generate electricity?

A mobius coil doesn't generate electricity by itself. If power is applied to function the mobius coil, positive and negative fields applied in opposing direction, then they cancel each others field out supposedly producing a scalar wave. A scalar wave is part of the Quantum theory of particle-wave duality.

How can electromagnetic waves be produced?

Any electric charge undergoing acceleration will produce Electromagnetic waves. This is by far the most common way.If an oscillating electric field is synchronized with an oscillating magnetic field of exactly the same frequency a beam of light will be produce where the two fields are orthogonal in all dimensions.


What is the phase relation between oscillating electric and oscillating magnetic fields in an electromagnetic wave?

The fields are in time phase and space quadrature.


What causes electric magnetic wave?

Electromagnetic waves are caused by changing electric fields which create magnetic fields, and changing magnetic fields which create electric fields. These waves propagate through space at the speed of light and carry energy. They are produced by accelerating charged particles or by oscillating electric currents.


As an electromagnetic wave travels its energy is carried through?

the oscillating electric and magnetic fields. These fields are perpendicular to each other and to the direction of the wave's propagation. Energy is transferred as the fields interact with charged particles in the medium through which the wave is traveling.


Can an electric current generate an electromagnetic wave?

Not a constant electric current but a changing one will generate electromagnetic waves.First: If you have a lone electron, and it is accelerated in any way, it will send off an electromagnetic wave. This is because a changing electric field generates a magnetic field.It is also true that changing magnetic field will generate an electric field. This is the reason that if you have an electric current, which is generating a magnetic field, and you change the current you generate an electromagnetic wave. To generate a continuous sinusoidal electromagnetic wave you continuously change the current sinusoidally.


How do working magnets generate magnetic fields?

Working magnets generate magnetic fields through the alignment of their atomic particles, specifically electrons, which creates a magnetic force. This force is what allows magnets to attract or repel other objects.


How does a vibrating electric charge produce an electromagnetic wave?

When an electric charge vibrates, it creates changing electric and magnetic fields. These changing fields propagate through space, creating electromagnetic waves. The oscillating electric field produces a magnetic field, and the changing magnetic field then produces an electric field, thus creating a self-sustaining wave.


Phase relationship between oscillating electric and magnetic fields?

nothing


What are two ways to produce electric fields electric fields are produced by charged particles or by changing magnetic fields?

One way to produce an electric field is through the presence of charged particles. When charged particles, such as electrons or protons, are stationary or in motion, they generate an electric field around them. Another way to produce an electric field is through changing magnetic fields. According to Faraday's law of electromagnetic induction, a changing magnetic field induces an electric field, causing the flow of electric charges.


Which describes an electromagnetic wave?

A transverse wave consisting of changing electric fields and changing magnetic fields


Oscillating electric and magnetic fields regenerate each other These oscillating fields perpetuate?

This phenomenon is known as electromagnetic wave propagation, described by Maxwell's equations. An oscillating electric field induces a magnetic field, which in turn produces an oscillating electric field. This interplay allows electromagnetic waves to propagate through space without the need for a medium.
