induced tension
scalar quantity equal to the line integral of a vector quantity along a path C from point a to point b in which charge carriers can be displaced:

where A and B are respectively a magnetic vector potential and the magnetic flux density at a point of the path, v is the velocity with which that point is moving, r is position vector, and t is time

Note – The induced voltage is equal to the time derivative of the linked flux corresponding to the path, with the positive or negative signs according to the convention in IEC 60375.

tension induite, f
grandeur scalaire égale à la circulation d’une grandeur vectorielle le long d’un chemin C reliant le point a au point b, dans lequel des porteurs de charge peuvent se déplacer:

A et B sont respectivement un potentiel vecteur magnétique et l’induction magnétique en un point du chemin, v est la vitesse de déplacement de ce point, r est le vecteur de position et t est le temps

Note – La tension induite est égale à la dérivée par rapport au temps du flux totalisé correspondant au chemin, avec les signes positif ou négatif selon la convention exposée dans la CEI 60375.
