Maxwell's correction to Ampère's law introduced:

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. _Source: syllabus Physics Ch 8 §8.2 (Maxwell's Equations + EMI link)_
