NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about electromagnetic induction is correct?
A
The maximum voltage generated in a coil is directly proportional to the number of turns in the coil.
B
Electromagnetic induction only occurs in stationary coils within a magnetic field.
C
The induced emf in a coil is always negative due to Lenz's law.
D
The induced emf is independent of the area of the coil in a magnetic field.
Correct Answer
Option A
Detailed Explanation
The maximum voltage generated in a coil is directly proportional to the number of turns, as indicated in the example regarding a rotating coil in a uniform magnetic field, where the voltage is calculated using the number of turns (N) as a factor.
