A changing electric field induces a current in a conductor through electromagnetic induction. This phenomenon is described by Faraday's law of electromagnetic induction, which states that a changing magnetic field around a conductor will induce an electromotive force (EMF) that can drive a current in the circuit.

How does a time-varying electric field lead to the generation of a magnetic field?
A time-varying electric field creates a changing electric flux, which in turn induces a circulating electric current. This current generates a magnetic field according to Ampre's law, leading to the generation of a magnetic field.
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.
How does a conducting loop move through a constant magnetic field affect the generation of electric current within the loop?
When a conducting loop moves through a constant magnetic field, it induces an electric current within the loop. This is due to the phenomenon of electromagnetic induction, where the changing magnetic field creates an electric field that drives the flow of electrons in the loop, generating an electric current.

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.
Can moving electrons through a magnetic field can produce an electric current?
Yes, a moving electron in a magnetic field can induce an electric current. This is the principle behind electromagnetic induction, where a changing magnetic field induces an electric current in a conductor.
How electric current have magnetic effect?
When an electric current flows through a conductor, it creates a magnetic field around the conductor. This is due to the movement of charged particles, such as electrons, which generate a magnetic field. The strength of the magnetic field is directly proportional to the amount of current flowing through the conductor.
In order to produce a current there must be a change of the magnetic field. True or False?
True. According to Faraday's law of electromagnetic induction, a changing magnetic field can induce an electromotive force (emf) in a conductor, resulting in the generation of an electric current.
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.
A moving magnet produces an electric current is this true?
A changing magnetic field produces an electric current, so yes. This is true.
Does an electric current produces a magnetic field?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
