Repulsion. Magnets do not like to join like poles together, which is why a north and a south pole attract each other.
The opposite ends of a magnet are called polar and nonpolar. One end attracts and the other repels.... opposite ends of two magnets attract.
The planet Earth has only two magnetic poles, north and south. They do not always stay in the same location, however.
== == Earth happens to have two North poles, but it is not necessary. * The geographic north pole is one of the two places where the axis of rotation meets the surface. All planets and stars have one geographic north pole and one geographic south pole. * The north magnetic pole is the point where the magnetic field points directly down, and the south magnetic pole is the point where the magnetic field points directly up. Earth happens to have one magnetic north pole and one magnetic south pole at the moment. Mars doesn't have any magnetic poles. Our sun often has dozens of magnetic north and magnetic south poles in or near its sunspots.
Nothing happens, except that now you have two magnets. The poles of a magnet are not actually localized at the two ends of the magnet but are inherent to the magnetic properties of the magnet. As the magnetic properties are not altered by a modification of the magnet such as cutting it in half, there will be no effect on the poles of the magnet.
North poles attract south poles, and the other way around as well. Two poles of the same kind will repel eachother.
The Geographical South Pole, The Magnetic South Pole and The Southern Pole of Inaccessibility.

they move away from each other!

There are two types of global poles; magnetic and geographic. Neither were invented. The magnetic poles are two points on the Earth where the magnetic field is most intense. The geographic poles are the northernmost and southernmost positions on the globe.
North poles attract south poles, and the other way around as well. Two poles of the same kind will repel eachother.
The Geographical South Pole, The Magnetic South Pole and The Southern Pole of Inaccessibility.
Electrons repel other electrons, and magnetic poles repel other magnetic poles which are the same, that is, north repels north and south repels south.
