Question
Write notes on Ampere-Maxwell law.
Solution
Maxwell modified Ampere’s law as
`oint vec"B" * vec"dl" = mu_0"i" = mu_0["i"_"c" + "i"_"d"]`
`oint vec"B"*vec"dl" = mu_0"i"_"c" = mu_0epsilon_0 ("d"phi_"E")/"dt"` ....(1)
where the total current enclosed by the surface becomes the sum of conduction current and displacement current. The equation (1) is known as Ampere – Maxwell law.
