In the early years of American football, the field had vertical lines as well as horizontal lines, creating the "gridiron" (or checkerboard) effect. The rule was that each play would begin in the square at which the previous play ended. The vertical lines were replaced by hash marks sometime around 1910-11.
Magnetic field lines do not have physical existence or substance; they are a visual representation of the magnetic field direction and strength. They are not tangible lines that can be touched or seen.
The infield lines are about three inches wide. The wider lines surrounding the field and end zones are a yard wide.

Ignoring the asymmetric drawings painted on the field (in the end zones, etc) depicting the teams playing, it has 2 lines of symmetry.
Kind of. If you were to look at an American football field from above, the way the chalk lines are laid out for the yard lines and end zones would make it look something like a gridiron.

The boundary lines at the ends of the field are "goal lines" or "end lines". The long boundary lines at the sides of the field are "touch lines" or "side lines". In FIFA Laws of the Game, Law 1 describes the field of play in more detail.
They are the same between the lines, but many NFL fields extend well beyond the sidelines
