Answer:
The magnetic line of force tends to bend away/move outwards from the south poles of both magnet causing a repulsive force between them.
Step-by-step explanation:
Magnetic line of force are forces acting on a bar magnet in the magnetic field. It specifies the direction in which a magnet tends to move when placed in the field.
For bar magnets with south poles, the magnetic line of force tends to move away from the south poles of both magnets thereby creating a force of opposition between them since like poles of a magnet repels each other.
