STANDARD Physics Lenz's Law MCQ Question
Type: MCQ-conceptual-Medium-Class 12
According to Lenz's law of electromagnetic induction
A
the direction of induced e.m.f. is such that it supports the change in magnetic flux
B
the relative motion between the coil and magnet produces change in magnetic flux
C
only the magnet should be moved towards coil for the generation of induced electric field
D
only the coil should be moved towards magnet for the production of induced emf.
Correct Answer
Option B
Detailed Explanation
The relative motion between the coil and the magnet produces change in the magnetic flux in the coil and the induced emf is always in such a direction that it opposes the change in the flux.
