Definition: 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:

U i = r a ( C ) r b ( A t +vB )dr MathType@MTEF@5@5@+=feaagCart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLnhiov2DGi1BTfMBaeXatLxBI9gBaerbbjxAHXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaeqabiGaciGacaqadmaadaqaaqaaaOqaaiaadwfadaWgaaWcbaGaaeyAaaqabaGccqGH9aqpdaWdXbqaamaabmaabaGaeyOeI0IaaGjbVpaalaaabaaccaGae8NaIyRaaGjbVJqadiaa+feaaeaacqWFciITcaaMi8UaaGjbVlaadshaaaGaey4kaSIaamODaiabgEna0kaa+jeaaiaawIcacaGLPaaacqGHflY1caqGKbGaamOCaaWcbaGaamOCamaaBaaameaacaqGHbaabeaalmaabmaabaGaae4qaaGaayjkaiaawMcaaaqaaiaadkhadaWgaaadbaGaaeOyaaqabaaaniabgUIiYdaaaa@574C@

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.
