Figure shows an amperian path \(ABCDA\). Part \(ABC\) is in vertical plane \(PSTU\) while part \(CDA\) is in horizontal plane \(PQRS\). Direction of circulation along the path is shown by an arrow near point \(B\) and at \(D\). \(\oint \vec{B} \cdot d \vec{l}\) for this path according to Ampere's law will be:
