IEVref: 121-11-24 ID: Language: en Status: Standard Term: protoflux Synonym1: linked flux [Deprecated] Synonym2: Synonym3: Symbol: Ψp Definition: scalar line integral of a magnetic vector potential A along a curve C ${\Psi }_{p}=\underset{\text{C}}{\int }A\cdot \text{d}r$ where dr is a vector line element Note 1 to entry: For a closed curve C, the protoflux is equal to the magnetic flux Φ through an arbitrary surface S limited by the curve C $\Phi =\underset{\text{C}}{\oint }A\cdot \text{ }\text{d}r=\underset{\text{S}}{\int }B\cdot {e}_{\text{n}}\text{\hspace{0.17em}}\text{d}A$ where B is the magnetic flux density and endA a vector surface element of S (see IEV 121-11-21). Note 2 to entry: The coherent SI unit of protoflux is tesla, T = s−2 kg A−1.
