They are small areas in a material in which lots of atoms are oriented in the same direction, thus providing a magnetic field. The material's atoms would have to have a magnetic moment. If an external magnetic field is applied to such a material, the magnetic domains have a tendency to align to the magnetic field. And no, they are not "everywhere"; they only happen in certain magnetic materials such as iron.
The shape of a magnet can impact its magnetic field by influencing the distribution and direction of the magnetic field lines. For example, a bar magnet will have a magnetic field that extends from one pole to the other, while a horseshoe magnet will concentrate the field between its poles. The shape can also affect the strength and direction of the magnetic field in different regions.
The strength of a magnetic field is typically measured in units of Tesla (T) or Gauss (G). For example, the Earth's magnetic field is around 25 to 65 microteslas. In comparison, an MRI machine produces a magnetic field of around 1.5 to 7 Tesla.
A Magnetic Force
Iron
One example of a non-magnetic metal is aluminum. It does not have magnetic properties because its atoms do not align in a way that creates a magnetic field.
The atmosphere of the earth is a magnetic filed

no. For example if u have a straight wire with a current running through it there will still be an electromagnetic field but it will not be magnetic. If u coil it around a magnetic object such as a nail for example u will get a magnetic field as the charge moves from the north to south around the object and back to the north through the object.

No, the Earth's Magnetic Field acts just like a BAR Magnetic. It has a North and South Pole and its magnetic lines of its force field are more tightly 'compressed' near the Poles than at the Equator. See the image below for an example, or Google "magnetic field lines".

Iron
A common example of this is a magnet. Magnets have a magnetic field around them and can attract certain materials like iron, nickel, and cobalt due to their magnetic properties.

I don't believe there is a special name for that, so you can just use a term similar to what you wrote in the question, for example, "a region with no magnetic field".
