What suggestion was done to correct discrepencies in Ampere circuital law ?

Explanation

Scientist Faraday suggested that time variant magnetic field produce electric field.
Maxwell suggested that electric field changing with time produces electric field.
Maxwell tried to obtain magnetic field in outside capacitor when it is connected with varying electric field. Maxwell found discrepancies in this law. This law is represented as,
`oint vec(B).vec(d)l=mu_(0)I+?`
Maxwell added term of .displacement current. to remove discrepencies in it.
