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 in a loop when there is a change in magnetic field direction?
When there is a change in the direction of the magnetic field in a loop, an induced current is generated in the loop in a direction that opposes the change in the magnetic field.
How can one determine the direction of induced current in a circuit?
The direction of induced current in a circuit can be determined using Lenz's Law, which states that the induced current will flow in a direction that opposes the change in magnetic field that caused it. This means that the direction of the induced current will be such that it creates a magnetic field that opposes the original change in magnetic field.
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 the induced emf in the coil when a magnetic field is applied?
When a magnetic field is applied to a coil, it creates an induced electromotive force (emf) in the coil. This emf is generated due to the change in magnetic flux through the coil, according to Faraday's law of electromagnetic induction.

Difference between back EMF and induced EMF?
An induced electromotive force (emf) is an induced voltage. Voltage (emf) causes current flow, and this induced voltage will cause a current that is called the induced current.We might also add that the induced current will cause a magnetic field to expand about the current path, and this field will "sweep" the conductor. The sweeping of the conductor by that expanding magnetic field will set up an emf that will oppose the emf that was creating it.CommentTechnically, there is no such thing as an 'induced current'. It is voltage that is induced. Any current flows as a result of that induced voltage being applied to a load. But that current is certainly NOT induced!
What is the direction of induced current in lenzs law?
According to Lenz's Law, the direction of the induced current is such that it opposes the change in magnetic flux that produced it. If the magnetic field through a loop is increasing, the induced current will flow in a direction that creates a magnetic field opposing that increase. Conversely, if the magnetic field is decreasing, the induced current will flow in a direction that attempts to maintain the original magnetic field. This principle ensures the conservation of energy in electromagnetic systems.
How induced current produce?
when a conductor moves accross a magnetic field or when magnetic field moves with respect to a stationary conductor for current to be induced, there must be relative motion between the coil and the magnetic.
How induced current is produce?

What does the lenz law state?
The direction of an induced emf or current is such that the magnetic field created by the induced current opposes the change in magnetic flux that created the current.
What is the statment of lenz law?
The direction of an induced emf or current is such that the magnetic field created by the induced current opposes the change in magnetic flux that created the current.
At what degree does a conductor have to pass through a magnetic field to get maximum induced current?
The induced current is maximum when the axis of the conductor, its velocity, and the magnetic field lines are all mutually perpendicular.
Why lenz's law can be applied only to closed loops?
Lenz's law and Faraday's law of Induction.The induced current causes a magnetic field according to Ampere's law, which itself has a flux through the closed loop. According to Lenz's law, the direction of the induced current and which results in the induced magnetic flux opposes the initial magnetic flux.
