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 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.

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.

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.
