Physics-Motional EMF
NEET Physics Motional EMF MCQ Question
Type: MCQ-fact-Medium-Class 12
What causes the separation of charges in a rod moving through a magnetic field?
A
Lorentz force acting on free electrons
B
Constant magnetic flux
C
Resistance in the circuit
D
Electric field from the battery
Correct Answer
Option A
Detailed Explanation
The separation of charges in the rod occurs due to the Lorentz force acting on the free electrons as the rod moves through the magnetic field, leading to the generation of emf across the ends of the rod.
