you see magnets are really boring and you who cares because appartently you will be using this all the time in real life
Magnetic fields are the reason why atoms make an object magnetic.
A Magnetic Domain is a cluster of billions of atoms that have magnetic fields lines up the same way.
A region in which the magnetic fields of atoms, or electron spin, are grouped together and similarly aligned.
MRI
The Zeeman effect is the splitting of single spectral lines into three or more in the presence of a magnetic field.

Magnetic fields are cause by the movement of charge , normally electrons each atoms has a magnetic moment
A region in which the magnetic fields of atoms, or electron spin, are grouped together and similarly aligned.
In non-magnetic materials,the magnetic moments of individual atoms are randomly arranged giving net zero magnetic moment such that these materials are not affected when an external magnetiv field is applied
cancel each other out. Source: Me and my 7 grade Text Book
Yes, that's the basic idea.
it is known as a magnetic domian.
MRI
As a general rule nothing, however if you have a ferroelectromagnet, a ferrous core surrounded by a conducting coil, then the atoms align their individual magnetic fields in the direction of the magnetic field created by the coils, causing all the magnetic fields to add together cumulatively, instead of canceling each other out.
Magnetic fields are stronger when cooled down. This is because the atoms that make up the magnetic material aren't moving as fast as a heated magnet's atoms. This means that the magnetic domains are less likely to move out of place and mess up the magnetic field.
