no correct description of magnetic field lines.
The density of magnetic field lines indicates the strength of the magnetic field. More closely packed lines suggest a stronger magnetic field, while widely spaced lines suggest a weaker field in that region. The direction of the magnetic field is indicated by the orientation of the field lines.
Magnetic field lines show the direction of the magnetic field, the magnitude of the magnetic field (closeness of the lines), and the shape of the magnetic field around a magnet or current-carrying wire.
The magnetic field lines are closest together at the poles of a magnet. This is where the magnetic field is strongest and the lines are most concentrated.
Magnetic field lines are closest together at the poles of a magnet, where the magnetic field is strongest. This is where the magnetic force is most concentrated.
Magnetic lines of force are called magnetic field lines.

Magnetic fields are produced because of moving electric charges, and visualizing the very complex mathematical relationships that fall under the magnetic field might become much easier if magnetic field lines were used. A higher density of field lines means a stronger magnetic field. Keep in mind that those lines do not actually exist; they are drawn only to visualize the strength of the magnetic field.
APEX: Field lines that are close together indicate a stronger magnetic field. They don't affect the magnet that created them. They never cross. They begin on north poles and end on south poles.
No, magnetic field lines close together indicate a stronger magnetic field, while magnetic field lines farther apart indicate a weaker magnetic field. The density of field lines represents the strength of the magnetic field in that region.

Magnetic field lines don't cross.
The lines that map out the magnetic field around a magnet are called magnetic field lines. These lines indicate the direction of the magnetic field and its strength at different points around the magnet. Magnetic field lines are closest together where the magnetic field is strongest and they form closed loops that do not intersect.
