Maxwell noticed this law was incomplete

James Clerk Maxwell noticed that Ampere's law could lead to contradictory results. Consider, for example, the case of an alternating current across a capacitor: On one hand, one obtains

Returning to our example, let's see how the 4th Maxwell Eq. lift the contradiction. First, lets find the magnetic field B using the loop G (shown in the figure) and the surface S1
