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 .

Pretty simple , as a matter of fact .
The tiny region in a magnet where all the atoms are grouped together and their poles are aligned is called a Domain.
the small group of atoms who have aligned magnetic fields are called magnetic domains. If enough magnetic domains in a crystal become aligned, the crystal exhibits macro-scale magnetism.
A magnetic domain
A magnetic domain.
magnetic domains. itdescribes a region within a magnetic material which has uniform magnetization. This means that the individual magnetic moments of the atoms are aligned with one another and point in the same direction. Below a temperature called the Curie temperature, a piece of ferromagnetic material undergoes a phase transition and its magnetization spontaneously divides into many tiny magnetic domains, with their magnetic axes pointing in different directions. Magnetic domain structure is responsible for the magnetic behavior of ferromagnetic materials like iron. The regions separating magnetic domains are called domain walls where the magnetisation rotates coherently from the direction in one domain to that in the next domain.

Each magnetic domain has a magnetic field. When an external magnetic field is applied, the magnetic domains will partially align, so the magnetic fields reinforce one another - instead of canceling one another, which is what happens when they are randomly distributed.
When air pressure is constant throughout a region of the atmosphere the region is in a state is called equilibrium.
A region in which the magnetic fields of atoms, or electron spin, are grouped together and similarly aligned.
The magnetic field. If it's an electromagnet, the electromagnetic field.
A Magnetic Force
That is called its magnetic field.
A Magnetic Force
Magnetic domains are microscopic areas of a solid where the atoms all have their magnetic moments aligned. If these domains are randomly aligned then a ferromagnetic material like iron or nickel will not have any permanent magnetism. If these domains start to align with each other the bulk material will show permanent magnetism. The area around a magnet where the force acts is the magnetic field.
If you mean the region of influence of the earth's magnetic field then its called the earth's magnetosphere

That's called the magnetic field.
