A magnet attract a piece of Iron is pull or push ? what about repulsion between similiar poles of two magnets. is it a pull or push?

Magnets are usually made of metal iron, or another material that has lots of iron in it, such as steel. Magnets can be of various shapes, but all of them have the ability to pull things towards themselves. This invisible force is called magnetism. Magnets only attract (pull) metals that are made of iron or that contain iron.
 Magnetism is concentrated around the poles (ends) of a magnet. A magnet has two poles, called the north pole and the south pole. The two poles may look the same but they behave differently.
 The poles of two magnets that are different or opposite will attract. Magnetic lines of force from north and south poles pull together and join. The poles of two magnets that are the same will repel or push each other apart.
