According to the modified Ampere's circuital law (Ampere-Maxwell Law), where \(i_c\) represents the conduction current and \(i_D\) represents the displacement current, the correct equation is:
| 1. | \({\oint \vec B. d\vec{l}=\mu_0\left(i_c+\varepsilon_0\dfrac{{d}\phi_E}{dt}\right)} \) |
| 2. | \( { \oint \vec B.d\vec{l}~=~\mu_0~\varepsilon_0\dfrac{{d}\phi_E}{ dt}} \) |
| 3. | \( { \oint \vec B.d\vec{l}=\mu_0{i}} \) |
| 4. | \( { \oint \vec B. d\vec{l}=\mu_0\left(i_c\dfrac{d\phi_E}{dt}{+i_D}\right)}\) |

Maxwell's modified form of Ampere's Circuital law is:
1. \(\oint{\vec{{B}}}.d\vec{s} ={0}\)
2. \(\oint{\vec{{B}}}.d\vec{l} ={\mathit{\mu}}_{0}{I}\)
3. \(\oint{\vec{B}}.d\vec{l}={{\mu}}_{0}{I}+\dfrac{1}{{\varepsilon }_{0}}\dfrac{dq}{dt}\)
4. \(\oint{\vec{B}}.d\vec{l} ={{\mu}}_{0}{I}+{{\mu}}_{0}{\varepsilon}_{0}\dfrac{d{{\phi}}_{E}}{dt}\)
1. \(\oint{\vec{{B}}}.d\vec{s} ={0}\)
