Concept:Magnetic field lines are visual aids whose spacing visually indicates the relative magnitude of the magnetic field vector in that region of space.
Solution:- By convention, the density of magnetic field lines (how closely packed they are) directly correlates to the strength of the magnetic field.
- Where lines are very close together, the field is remarkably strong (like near the poles of a magnet).
- Conversely, where lines are farthest apart, the magnetic field is at its weakest.
- Therefore, the statement "Magnetic field is strongest when lines are farthest" is fundamentally incorrect.
Why other options are incorrect:Options A, B, and C are all true, factual properties of standard magnetic field mapping, meaning they are not the "incorrect" statement being asked for.
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.
