NEETPhysicsElectromagnetic Induction
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : The electric field created by time-varying magnetic field is non-conservative. Reason (R) : The line integral of induced electric field in a closed loop is always equal to zero. 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 the electric field created by a time-varying magnetic field is non-conservative. For a conservative electric field, the line integral around a closed loop is zero ( E d I = 0 ). However, according to Faraday's Law of Induction, E d I = - d _B dt , which is generally non-zero when there is a changing magnetic flux. This non-zero line integral signifies that the induced electric field is non-conservative. So, Assertion (A) is true. - Reason (R) states that the line integral of induced elec
