Since the field is everywhere you could in principle draw field lines through every point which would make the field line drawing just a space filled with black. So the artist decides how often to represent a line, just so that the density of the lines referents the strength. That is, if you take a field line map and redraw it, taking only every other line, you’re still representing the same field, just at a different sampling. If you take the same field line map and double the number of lines, it’s still the same field line map, just at a different sampling. If you like, look at a topographical map with iso lines. You could draw iso lines for every inch of elevation but it’d be impossible to read. So the map drawer CHOOSES the interval of elevations to draw an iso line for. Changing the interval doesn’t change the terrain, just the density of iso lines drawn. Note there is a similarity here. On a topo map, the closer the iso lines are to each other, the steeper the incline. There’s actually an even deeper connection between field lines and iso lines that I’m not covering here, but that TOO is covered well in about a page in a textbook. Nothing “makes” the line other than an artist. It’s just a way of representing a vector field. You could “make” field lines for a hedgehog too, just by treating the quills as little arrows on its skin to follow from one place on its hide to the next with a pen. And the spacing of your lines would be inversely proportional to the length of the spine where you’re at. NOTHING MOVES ALONG AN ARTIST’S FIELD LINE EXCEPT HIS PEN. > Do they get really far apart? > -- Odd Bodkin — Maker of fine toys, tools, tables
