This you see as the north pole forming near the north pole of the solenoid. Like poles repel, unlike poles attract is kind of a misleading analogy(I find it strange that I realized this after reading your question). What actually is happening is that the tiny magnetic dipoles inside the magnetic material(a bar of iron, for example) align with the direction of the magnetic field.
Every magnet has at least one north pole and one south pole. By convention, we say that the magnetic field lines leave the north end of a magnet and enter the south end of a magnet.This is an example of a magnetic dipole (âdiâ means two, thus two poles). If you take a bar magnet and break it into two pieces, each piece will again have a north pole and a south pole.
