Practice question
Question
A coil is wound tightly around a core material. If the current through it changes rapidly, the induced emf opposing this change is an example of which phenomenon?
Explanation
This is self-induction, where a changing current in a coil induces an emf that opposes the change, proportional to the coil’s self-inductance. This follows from latest NCERT 2026-27 principle explaining the concept clearly for NEET students in simple steps as per rationalized syllabus.
