NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): The maximum voltage generated in a rotating coil in a magnetic field is directly proportional to the number of turns of the coil. | Reason (R): Increasing the number of turns of the coil increases the magnetic flux linkage, which enhances the induced emf.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
The NCERT context mentions that the maximum voltage generated, e₀ = NBA(2πn), is directly proportional to the number of turns, N. The reason correctly explains that more turns increase flux linkage, enhancing the induced emf.
