# Which magnetic force is stronger? Electron or proton?

Assume the particles generates the magnetic field with their own spin. No motions except spin.(they have their intrinsic angular momentum.) Then which one generates stronger magnetic force?

I've seen the formula which represents the magnetic moment of the 1/2 spin particles with charge $q$, mass $m$, $\vec{\mu}=\frac{g_sq}{2m}\vec{S}$ where $g_s$ called g-factor.

But I can't understand the formula.

Let me ask a question, which magnetic force is stronger between electron and proton?
