IEVref: 121-11-24 ID: Language: en Status: Standard Term: linked flux Synonym1: Synonym2: Synonym3: Symbol: Ψ Definition: scalar line integral of a magnetic vector potential A along a curve C: $\Psi =\underset{\text{C}}{\int }A\cdot \text{d}r$ where dr is the vector line element NOTE 1 – For a closed curve C, the linked flux is equal to the magnetic flux through any surface S bounded by the curve: $\underset{\text{C}}{\oint }A\cdot \text{d}r\text{\hspace{0.17em}}=\text{\hspace{0.17em}}\underset{\text{S}}{\int }B\cdot {e}_{\text{n}}\text{d}A$ where B is the magnetic flux density and endA the vector surface element. NOTE 2 – For a coil with N turns, the linked flux is approximately equal to NΦ where Φ is the magnetic flux through any surface bounded by one turn.
