NEETPhysicsElectromagnetic Induction
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : A time varying magnetic field induces an electric field. Reason (R) : An inductor always tends to keep the flux constant. 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
C. (A) is true but (R) is false.
Step-by-step solution
- Assertion (A) states that a time-varying magnetic field induces an electric field. This is a direct consequence of Faraday's Law of Electromagnetic Induction, which states that a changing magnetic flux (often due to a time-varying magnetic field) induces an electromotive force (EMF), and this EMF is associated with an induced electric field. So, Assertion (A) is true. - Reason (R) states that an inductor always tends to keep the flux constant. While inductors do oppose changes in current (and thus changes in magn
