NEETPhysicsElectromagnetic Induction
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : The direction of induced current is always such as to oppose the change that causes it. Reason (R) : The direction of induced current is given by Lenz's law. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A).
- BBoth (A) and (R) are true and (R) is NOT the correct explanation of (A).
- C(A) is true but (R) is false.
- D(A) is false but (R) is true.
Correct answer
A. Both (A) and (R) are true and (R) is the correct explanation of (A).
Step-by-step solution
- Assertion (A) states that the direction of induced current always opposes the change that causes it. This is a direct statement of Lenz's Law, which is a fundamental principle of electromagnetic induction. So, Assertion (A) is true. - Reason (R) states that the direction of induced current is given by Lenz's law. This is also a true statement, as Lenz's Law explicitly defines the direction of induced current in a way that aligns with the principle of energy conservation (by opposing the change). - Furthermore, Re
