Definition: | scalar line integral of a magnetic vector potential along a curve C:A$\Psi ={\displaystyle \underset{\text{C}}{\int}A\cdot \text{d}r}$ where d NOTE 1 – For a closed curve C, the linked flux is equal to the magnetic flux through any surface S bounded by the curve: $\underset{\text{C}}{\oint}A\cdot \text{d}r\text{\hspace{0.17em}}=\text{\hspace{0.17em}}}{\displaystyle \underset{\text{S}}{\int}B\cdot {e}_{\text{n}}}\text{d}A$ where e_{n}dA the vector surface element.
