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:

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 where Φ is the magnetic flux through any surface bounded by one turn.
