Even static electrons have magnetic field due to the charged particles
spinning on their axis (moving electric charge).

There is no net effect however because for each electron in an atom which
spins clockwise another must spin anticlockwise (Pauli exclusion principle)
so they line up in pairs where North pole of  one of the " partners" ends up
pointing to South pole of the other (and vice-versa) so no magnetic field
gets out.
