Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Force
Concept:

Fleming's Right-Hand Rule maps the 3D vectors of electromagnetism in a generator.

Solution:

  • Index finger = Magnetic field (North to South).


  • Middle finger = Induced current direction.


  • Thumb = Direction of the motion of the conductor, which represents the applied mechanical Force.


Why other options are incorrect:

The magnetic field is the index finger. Induced current is the middle finger. Electric field is not directly represented in this specific generator rule.

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.
