Magnetic Flux and Electric Field – Rankers Physics

Magnetic Flux: Practice Problem & Solution

Assertion (A): A changing magnetic flux induces an electric field. Reason (R): An inductor always tends to keep the flux constant.  
(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)
(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(3) (A) is true but (R) is false
(4) Both (A) and (R) are false

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Magnetic Flux. Understanding the underlying formula is key to arriving at the correct answer below:

Faraday's Law states a changing magnetic flux induces an electric field. Inductors oppose change in flux, but don't keep it constant. Hence, Assertion is true and Reason is false.
