Maxwell's correction to Ampère's law introduced:
AConduction current only
BDisplacement current term
CMagnetic monopoles
DQuantised charge
Answer & Solution
Correct answer: B. Displacement current term
1. Maxwell added the DISPLACEMENT CURRENT ε₀ dΦ_E/dt to Ampère's law.
2. This was needed to make the equations consistent in regions where the conduction current is discontinuous (e.g., between capacitor plates).
3. It enabled prediction of electromagnetic waves and unified electromagnetism with optics.
