Magnetic field lines don't cross.
Never
No, they don't.
Actually, they NEVER do.
No, magnetic field lines do not cross each other at any point. This is a fundamental property of magnetic fields known as the "no crossing rule". If lines were to cross, it would imply the existence of multiple directions for the magnetic field at that point, which is physically impossible.
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.
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.
The list of choices submitted with the question containsno 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.
They are called the magnetic 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 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.
