Summary
[edit]DescriptionDisplacement current in capacitor.svg |
English: Diagram of a widely used example demonstrating need for the displacement current term in Maxwell's equations. The diagram shows a capacitor being charged by current The equation says that the integral of the magnetic field But surface So without the displacement current term Ampere's law fails; it gives different results depending on which surface is used, which is inconsistent. The 'displacement current' term provides a second source for the magnetic field besides current; the rate of change of the electric field James Clerk Maxwell added the displacement current term to Ampere's law around 1861. Example taken from Feynman, Richard; Robert Leighton; Matthew Sands (1964) The Feynman Lectures on Physics, Vol.2, Addison-Wesley, USA, p.18-4, using slightly different terminology. |
