NEET Physics (general) MCQ Question
Type: MCQ-fact-Hard-Class 12
What is the formula used to calculate the maximum voltage generated in a rotating coil within a magnetic field?
A
e₀ = NBA(2πn)
B
e₀ = NABn
C
e₀ = BAn²
D
e₀ = N(2πA)n
Correct Answer
Option A
Detailed Explanation
The maximum voltage generated in a coil rotating in a magnetic field is calculated using the formula e₀ = NBA(2πn), where N is the number of turns, A is the area of the coil, B is the magnetic field strength, and n is the frequency of rotation.
