What is the direction of the induced current in a coil when it is exposed to a changing magnetic field?
When a coil is exposed to a changing magnetic field, an induced current is generated in the coil. The direction of this induced current is such that it creates a magnetic field that opposes the change in the original magnetic field. This phenomenon is described by Faraday's law of electromagnetic induction.
What is the direction of the induced current when a magnetic field is rapidly changing in a coil of wire?
When a magnetic field is rapidly changing in a coil of wire, an induced current is generated in the wire. The direction of this induced current is such that it creates a magnetic field that opposes the change in the original magnetic field. This phenomenon is described by Faraday's law of electromagnetic induction.
What is induced electric field?
An induced electric field is a field that is created in a region in response to a changing magnetic field. According to Faraday's law of electromagnetic induction, a changing magnetic field induces an electric field in the surrounding space. This phenomenon is the basis for the operation of devices such as generators and transformers.
How can current be induced in a conductor?
Current can be induced in a conductor by changing the magnetic field around it. This change in magnetic field creates an electromotive force (EMF) within the conductor, which in turn causes the flow of current. This phenomenon is known as electromagnetic induction and is the basis for the operation of generators and transformers.
What factors determine the magnitude of induced current in a wire loop when exposed to a changing magnetic field?
The magnitude of induced current in a wire loop when exposed to a changing magnetic field is determined by factors such as the strength of the magnetic field, the rate of change of the magnetic field, the number of turns in the wire loop, and the resistance of the wire.

What can induce an electrical current in a wire?
An electrical current can be induced in a wire by a changing magnetic field passing through the conductor. This phenomenon is known as electromagnetic induction, and it is the basis for the operation of generators and transformers. Moving the wire through a magnetic field or changing the magnetic field around the wire can result in the generation of an electrical current.
How does the frequency of a changing magnetic field compare with the frequency of the alternating voltage that is induced?
A changing magnetic field generates an electric field and alternating currents are accompanied (or caused) by alternating voltages.
Can we create magnetic field to electric field?
we can create electromotive force (and electric current) by changing magnetic field linked with a conductor by the principle of electromagnetic induction which is governed by the Faraday's and Lenz's law. But electric field is created by statical electricity.
Electric current is induced when?
electric current is induced when a conductor (such as a wire) moves through a magnetic field or when there is a change in the magnetic field surrounding a conductor. This phenomenon is known as electromagnetic induction, discovered by Michael Faraday in the 1830s.
What is the induced emf in case (a)?
In case (a), the induced emf is the electromotive force generated in a coil or conductor due to a changing magnetic field.
When a magnetic field in a wire are moved near each other the voltage produced is said to be?
Induced
What is maxwell's counter part to faradays law?
A magnetic field is induced in an region of space in which and electric field is changing with time.
