|
The field lines combine with the lines around the second south pole.
|
|
|
The field lines overlap with the lines from the second south pole.
|
|
|
The field lines bend toward the second south pole.
|
|
|
The field lines bend away from the second south pole.

Detailed explanation-1: -How are the magnetic field lines near the south pole of a magnet affected when a second south pole is brought near it? The field lines bend away from the second south pole.
Detailed explanation-2: -The south pole of a magnet is brought near an end A of another magnet. The two repel each other.
Detailed explanation-3: -However, when we bring South pole of bar magnet near the magnetic compass, the needle will be deflected towards the magnet as shown in the second figure.
Detailed explanation-4: -Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. Therefore, the magnetic field lines of the earth run from the southern geographic hemisphere towards the northern geographic hemisphere.
Detailed explanation-5: -The stronger the magnetic field, the closer the field lines are to each other. Magnetic field lines are crowded towards the poles because the magnetic field is stronger near the poles.
