How do magnets work?

>>9059581
magnetic field is invisible but is responsible for the most notable property of a magnet

>Each atom has an magnetic moment due to electron spinning(works like a current loop)
>atoms with dipole moment in same direction align because 4 buzzwords
>anisotropic energy, magnetostatic energy, magnetostriction, bloch wall
>these locally aligned "domains" align in one direction with all other domains under magnetic field
>magnetic field is removed, retentivity happens
>shit werkz
