Changing electric and magnetic fields consist of producing electric currents, electromagnetic waves, or inducing magnetic fields in a given medium. This change can be observed through various phenomena, such as electromagnetic induction, electromagnetic radiation, or the propagation of electromagnetic waves.
What else can I help you with?
A wave that consists of changing electric and magnetic fields is called?
Magnetic field
Why is a vibrating electric field an example of an electromagnetic wave?
A vibrating electric field produces a changing magnetic field, which then generates a changing electric field and so on, creating a self-propagating wave. This wave consists of oscillating electric and magnetic fields perpendicular to each other and to the direction of wave propagation, thus exhibiting the characteristics of an electromagnetic wave.
Can a changing magnetic field produce a steady electric field?
Yes, a changing magnetic field can induce a steady electric field. This is described by Faraday's law of electromagnetic induction, where a changing magnetic field creates an electric field in the surrounding space.
What does a changing magnetic field induce in a conductor?
A changing magnetic field induces an electric current in a conductor.
How does a time-varying magnetic field lead to the generation of an electric field?
A time-varying magnetic field creates a changing magnetic flux, which induces an electric field according to Faraday's law of electromagnetic induction. This electric field is generated as a result of the changing magnetic field, leading to the production of an electric current.

What wave consists of changing electric and magnetic field?
Electromagnetic radiation (e.g., light) fits the bill.
What does a changing magnetic field induce in a conductor?
A changing magnetic field induces an electric current in a conductor.

Will changing the electric field will have no effect on the magnetic fields of a body?
Changing the electric field in a region can induce a magnetic field according to Maxwell's equations. This is known as electromagnetic induction. So, changing the electric field can indeed have an effect on the magnetic fields of a body.
How does a changing magnetic field produce an electric field according to electromagnetic theory?
According to electromagnetic theory, a changing magnetic field induces an electric field. This phenomenon is known as electromagnetic induction, where the changing magnetic field creates a force that causes electrons to move, generating an electric current.
When a blank wave that is produced by a vibrating electric charge is an electromagnetic wave?
When a vibrating electric charge produces a changing electric field, it in turn generates a changing magnetic field, leading to the creation of an electromagnetic wave. This wave consists of oscillating electric and magnetic fields that propagate through space at the speed of light.
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.
What causes a electromagnetic wave?
An electromagnetic wave is caused by the vibration of electric and magnetic fields propagating through space. When an electric charge accelerates, it creates a changing electric field, which in turn generates a magnetic field. The changing magnetic field then creates a changing electric field, and this cyclical process results in the formation of an electromagnetic wave.
Do Electromagnetic waves consist of changing electric and magnetic fields?
Yes, that is the whole idea of an electromagnetic waves. A changing electric field generates a changing magnetic field; a changing magnetic field generates a changing electric field; and the two of them propagate as a wave at the speed of light.
