NEET Physics Motional EMF MCQ Question
In the diagram shown above, if a conductor of length L moves with a velocity v perpendicular to a uniform magnetic field B, which expression correctly represents the induced motional emf?
B * L * v
B * v / L
L * v / B
B / (L * v)
Correct Answer
Detailed Explanation
The induced motional emf in a conductor moving through a uniform magnetic field is given by the product of the magnetic field strength B, the length of the conductor L, and its velocity v, as described in the NCERT context on motional emf.
