NEET Physics Motional EMF MCQ Question
Type: MCQ-fact-Easy-Class 12
What is the formula for calculating the induced emf in a conductor moving perpendicular to a magnetic field?
A
ε = B * v * L
B
ε = B * I * R
C
ε = m * a * t
D
ε = F * d
Correct Answer
Option A
Detailed Explanation
The induced emf in a conductor moving at right angles to a magnetic field is given by the formula ε = B * v * L, where B is the magnetic field strength, v is the velocity of the conductor, and L is the length of the conductor in the field.
