Official Correct Choice:
Option C: Magnetic flux
Concept:

The Weber (Wb) is the official SI unit for a specific electromagnetism scalar quantity.

Formula:

$$ 1 \ \text{Wb} = 1 \ \text{T} \cdot \text{m}^2 $$

Solution:

  • By standard international agreement (SI units), the Weber is dedicated to measuring the total magnetic field traversing an area.


  • This physical quantity is exclusively known as Magnetic flux.


Why other options are incorrect:

Option A (Conductance) uses Siemens. Option B (Current) uses Amperes. Option D (Electric flux) uses Newton-meters squared per Coulomb (\( \text{N \cdot m}^2 / \text{C} \)).

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.
