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.

Which law gives the direction of induced current?

LENZ LAW gives the direction of induced current.


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.


Who formulated a law for determining the direction of the induced current in a conductor?

There is no such thing as an 'induced current'. What is 'induced' is a voltage. If the conductor into which that voltage is induced forms a complete circuit, then a current will result. But it's the voltage that's induced, NOT the current! The direction of the induced voltage is explained by Lenz's Law which, in simple terms, tells us that the direction of the inducted voltage is always such that it will oppose the change in current that causes it. So the induced voltage will oppose any increase in current, but will act in the same direction as a reduction in current.


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 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 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 lentz law in magnatism?

IF by Lentz law, you mean Lenz's law it is the law that for current to be induced through a wire with a magnetic field work must be done to push the magnet into the field and to pull it out of the field. "An induced current is always in such a direction as to oppose the motion or change causing it" (http://en.wikipedia.org/wiki/Lenz%27s_law)


What are some examples of Lenz's Law practice problems and how can they be solved effectively?

Examples of Lenz's Law practice problems include calculating the direction of induced current in a coil when a magnet is moved towards or away from it, or determining the direction of induced current in a rotating loop within a magnetic field. These problems can be effectively solved by applying Lenz's Law, which states that the induced current will always flow in a direction that opposes the change in magnetic flux that caused it. By understanding this principle and using the right-hand rule to determine the direction of induced current, these problems can be solved accurately.


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.


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.


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.
