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.
How can we use Lenz's Law to determine the direction of induced current in each case?
Lenz's Law states that the direction of the induced current in a circuit is such that it opposes the change in magnetic flux that caused it. By applying Lenz's Law, we can determine the direction of the induced current by considering the direction of the changing magnetic field and the direction of the induced current that would oppose that change.
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 the direction of the induced electric field?
The direction of the induced electric field is perpendicular to the change in magnetic field.

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.
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.

What law states that the induced current is always in such a direction as to oppose the change in the magnetic field that generated it?
It is called Lenz's law. Refer to the below related link for its Wikipedia article. It is a direct result of Faraday's law. If you look at the equation.. ε = - dΦ/dt it is basically the negative sign that says the magnetic field of the induced current will be in the oppose direction of the change in the magnetic field. Do the following things. • Curl the fingers of your right hand. • Let your thumb represent the direction that the magnetic flux is increasing. • Because of the negative sign, the electric field, and thus the generated current will be in the opposite direction of you fingers. • So flip your hand over so that your fingers point in the opposite direction. • Now your thumb points in the opposite direction and that represents the direction of the magnetic field that the current generates.
What is lenz law of electromagnetic induction?
Lenz's law states that 'for a current induced in a conductor by a changing magnetic field, the current is in such a direction that its own magnetic field opposes the change that produced it.'
Why does the induced current opposes the original cause in lenz's law?
The induced current creates a magnetic field that opposes the original cause of it because it is trying to resist the change in magnetic field in the area and the only way to do that is to create an equal and opposite magnetic field which leads to the induced current.
Define the term induced current?
a current can be induced by changing the area of a coil in a constant magnetic field. By Faraday's Law: the induced current is proportional to the rate of the change of flux in a loop of wire. With magnetic flux being defined as the product of the magnitude of the magnetic field and the area of the loop. The direction of the current is found from Len's Law: The induced current produces an induced magnetic field that opposes the change of flux causing the current.CommentYou don't induce a current, you induce a voltage. And Faraday's Law states that the induced voltage, not current, is proportional to the rate of change of flux! If the coil is open circuited, a voltage is still induced into the coil but no current will flow. For current to flow, the coil must be connected to a load (or short circuited), and this current is dependent upon the values of the induced voltage and the resistance of the load.
