Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Electromagnetic inductions
Concept:

An electrical generator converts mechanical energy into electrical energy by moving a conductor through a magnetic field.

Solution:

  • According to Faraday's Law, when a coil rotates in a magnetic field, the changing magnetic flux induces an EMF. This overarching process is known as electromagnetic induction.


Why other options are incorrect:

Mutual induction is for transformers. Self-induction applies to single inductors/chokes. Electrostatic induction involves static charges, not magnetic fields.

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.
