Propolis Cognitive Error Autopsy

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

The direction of induced electromotive forces and currents must strictly adhere to energy conservation.

Solution:

  • Lenz's Law dictates that nature resists change in magnetic flux. If a magnet is pushed toward a coil, the coil induces a magnetic pole that pushes back, opposing the motion.


Why other options are incorrect:

Faraday's Law calculates the magnitude of the EMF. Ampere's Law relates current to magnetic fields. Joule's Law calculates electrical heat generation.

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.
