STANDARD Physics Lenz's Law MCQ Question
According to Lenz's law of electromagnetic induction
the direction of induced e.m.f. is such that it supports the change in magnetic flux
the relative motion between the coil and magnet produces change in magnetic flux
only the magnet should be moved towards coil for the generation of induced electric field
only the coil should be moved towards magnet for the production of induced emf.
Correct Answer
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.
