Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Lenz's law
Concept:

The directionality of electromagnetic induction is governed by the conservation of energy.

Solution:

  • The textbook definition of Lenz's Law is exactly the quote provided: The direction of an induced current is always such that its magnetic field opposes the change in magnetic flux that caused it.


Why other options are incorrect:

Faraday's law calculates the magnitude of the EMF but does not dictate its direction explicitly without Lenz's law. Joule's law relates to resistive heating.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
