Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Induced current
Concept:

Fleming's Right-Hand Rule is a mnemonic used to determine the direction of induced current when a conductor moves through a magnetic field (generator effect).

Solution:

  • The Thumb represents the direction of the applied Motion (or Force).


  • The First (Index) finger points in the direction of the Magnetic Field (North to South).


  • The Second (Middle) finger is extended orthogonally to represent the direction of the Induced current.


Why other options are incorrect:

Option A and D refer to the thumb. Option B refers to the first (index) finger.

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.
