= Magnetic dipole
{title2=tiny idealized magnet}
{wiki}
A tiny idealized magnet! It is a very good model if you have a small strong magnet interacting with objects that are far away, notably other <magnetic dipoles> or a constant magnetic field.
The cool thing about this model is that we have simple explicit formulas for the <magnetic field> it produces, and for how this little magnet is affected by a magnetic field or by another <magnetic dipole>.
This is the perfect model for <electron> <spin>, but it can also be representative of macroscopic systems in the right circumstances.
The intuition for the name is likely that "dipole" means "both poles are on the same spot".
