Maxwell’s generalisation of Ampere’s circuital law
The source of a magnetic field is not just the conduction electric current, but also the time rate of change of electric field. Or the total current i is the sum of the conduction current denoted by ic, and the displacement current denoted by,
The Amperes circuital law is modified as follows,
This is called Ampere Maxwell law.
