magnetic lines of force

[mag′ned·ik ′līnz əv ′fȯrs]
(electromagnetism)
Lines used to represent the magnetic induction in a magnetic field, selected so that they are parallel to the magnetic induction at each point, and so that the number of lines per unit area of a surface perpendicular to the induction is equal to the induction. Also known as magnetic flux; magnetic lines of flux.
