A field line is a locus that is defined by a vector field and a starting location within the field. Field lines are useful for visualizing vector fields, which are otherwise hard to depict. Note that, like longitude and latitude lines on a globe, or topographic lines on a topographic map, these lines are not physical lines that are actually present at certain locations; they are merely visualization tools.

Famous quotes containing the words field and/or line:
“Love to chawnk green apples an’ go swimmin’ in the
lake.—
Hate to take the castor-ile they give for belly-ache!

me,
But jest ‘fore Christmas I’m as good as I kin be!”
—Eugene Field (1850–1895)
“One line typed twenty years ago
can be blazed on a wall in spraypaint
to glorify art as detachment
or torture of those we
did not love but also
did not want to kill.”
—Adrienne Rich (b. 1929)
