Assertion and Reasoning Type Questions: Lenz's Law

Assertion: Lenz’s law violates the principle of conservation of energy.
Reason: Induced emf always opposes the change in magnetic flux responsible for its production.

Explanation:
Lenz's law is a fundamental law of electromagnetism that is used to determine the direction of induced current as well as its magnitude. According to Lenz's law, the direction of induced current is such that it opposes the change in magnetic flux that produces it.

Conservation of Energy:
The principle of conservation of energy states that energy cannot be created or destroyed but it can only be converted from one form to another. Therefore, the total amount of energy in a closed system remains constant.

Explanation of Assertion:
When a magnet is moved towards a coil, an induced current is produced in the coil in opposition to the motion of the magnet. This induced current produces a magnetic field that opposes the motion of the magnet. As a result, the magnet experiences a force that opposes its motion. This force does work on the magnet and therefore energy is dissipated. This energy is not conserved, which violates the principle of conservation of energy. Hence the Assertion is correct.

Explanation of Reason:
The reason given for the assertion is that induced emf always opposes the change in magnetic flux responsible for its production. This is also true because of Lenz's law. When there is a change in magnetic flux, an induced emf is produced in a coil. This induced emf produces a current that creates a magnetic field that opposes the change in magnetic flux. This opposing magnetic field does work on the source of the magnetic field, which results in a loss of energy. Hence the Reason is correct and it is a correct explanation of the Assertion.

Conclusion:
Both the Assertion and Reason are correct, and the Reason is a correct explanation of the Assertion. Therefore, the correct answer is option 'A'.

Lenz’s law (that the direction of induced emf is always such as to oppose the change that cause it) is direct consequence of the law of conservation of energy.
