Within a magnet, the separate poles are composed of domains, regions where the individual atoms are aligned with parallel magnetic moments.
The group of atoms are considered "polarized" when their magnetic properties are aligned - read about magnetism and magnet properties.
Magnetic Domain
A magnet, or a magnetic domain.

A Magnetic Domain is a cluster of billions of atoms that have magnetic fields lines up the same way.
domains
A region in which the magnetic fields of atoms, or electron spin, are grouped together and similarly aligned.
The atoms in a magnet are arranged in some kind of lattice, but the arrangement of the atoms is not what is important. What is important is that the magnetic dipoles of a good portion of the atoms are all "pointing" in the same direction. The aligned atomic magnetic dipoles form groups called magnetic domains, and these are locked in place making the magnet a permanent magnet. It "permanently" holds its magnet field, and is said to be a permanent magnet. And all because the magnetic domains in the ferromagnetic material are largely aligned.

Technically impossible . In a rock , ferromagnetism can create poles , but not in atoms . Atoms cannot be magnetic . Molecules can be polar , which leads to Van der Waals links , but a region's molecule cannot become all lined in the same directions . http://www.youtube.com/watch?v=4VmMr9TWzY4 http://media-2.web.britannica.com/eb-media/65/265-004-9B256ADC.gif Pretty simple , as a matter of fact .
If a magnet doesn't stick to a material, that means that the material is non-magnetic. Every individual atom is a magnet, but in a magnetic material, there are groups of atoms (called "magnetic domains") that have their magnetic directions aligned. An outside magnetic field in such materials will align some of the magnetic domains in the direction of the magnetic field.

magnetic alignment
A region in which the magnetic fields of atoms, or electron spin, are grouped together and similarly aligned.
The atoms are not aligned in one direction known as vectors. Such alignment is necessary for magnetic properties to occur.
The atom's electrons spin in an orchestrated manner aligned parallel to each other. This rearranges the atoms into tiny bar magnets with two poles commonly referred to as north and south.A2 a small group of similarly-aligned magnets is called a magnetic domain.
The primary difference is that in materials that can be used as magnets, the atoms can form what are called magnetic domains. Individual atoms and small groups of them form these domains, and the domains can be caused to "face the same way" when exposed to a magnetic field. When the field that aligned them is removed, some of the domains don't return to their previous orientation. They stay aligned leaving a residual magnetic field. The materials that cannot be used magnets don't have magnetic domains. If you heat magnetic material and expose it to a strong magnetic field while it's hot (like at or above its Curie temperature), and then you apply a strong magnetic field and maintain the field while cooling it down, the field "impressed" on the material will largely stay there and you've made a permanent magnet.

Some objects are not attracted by magnets because they are not metalic. If the Magnet just attracts metalic minerals, definitely only metalic are attracted and not non-metalic..
