A magnet with two poles, such as a bar magnet, is called a magnetic dipole. One end points to the north & is considered the north pole, the end that points to the south is considered the south pole. The best way to visualize these two poles is to cut a magnet in half, creating a north pole and a south pole.
Lines of force are three-dimensional, surrounding a bar magnet on all sides. When opposite poles of a magnet are brought together, the lines of force join up and the magnets pull together.
.
If the north pole of a magnet is brought near the south pole of another magnet, the magnetic force will pull the magnets together. However, two north pole or two south poles brought together would repel each other. In other words, like repels like and the old saying, opposites attract! Why does this happen? That would be explained by what is known as the magnetic field. The magnetic field around a magnet is where the force of the magnetism can be felt. It is invisible, but you can get an idea of what it looks like by this simple example.
Take a magnet and place a piece of paper over it. On top of the paper (and above the magnet) sprinkle
iron fillings. The fillings arrange themselves along the lines of the magnetic force, making the lines visible.
A magnetic force can also be thought of as set of imaginary lines called lines of force. These lines are thought of as going out from the north pole of a magnet, looping around, and returning to the magnet at its south pole. The magnetic field is the strongest at the poles and is where the lines lie closest to each other. This explains why a compass works. The needle of a compass is actually a magnet. It normally points north along one of the earths magnetic field lines. But a strong bar magnet placed next to the compass will cause the needle to point along on of the bar magnet ës field lines.

cuz from noth pole magnetic field of lines come out
and from south pole they diverge in means from one pole it can attaract and from other it repel those things which also have magnetic field
hence just imagine
if one mag1 noth pole is placed near to the soth pole of mag2
from one mag line is coming out and other is ready to take magnetic field then definetly it will attaract each other

Obviously, Why does a male attracts a female (Mostly) hehe???
Ya, all metals have domains in them but they are scattered in different directions, magnets have a regular direction of domains, so +ve domain attracts -ve domain.

UNLIKE POLES ATTRACT EACH OTHER, FOR THIS I WILL GIVE YOU AN EXAMPLE.
in ramayana take ravanan to be the negative charge and sita to be the positive charge. in the story ravanan attracts sita. this is the proof.
