Atomic Electric Current & Ferromagnetism In a permanent magnet, all the magnetic dipole moments are aligned to generate it. However, apparently the orbital angular momentum of the electron about the nucleus also contributes to the magnetic field, but in quantum mechanics we learn that the atom is a stationary state, so how can orbital angular momentum induce a magnetic field?
Also, we're taught that magnetic fields are generated by moving charges, so when we first learn electrostatics we can ignore magnetism. But the stationary electrons we're concerned with still have magnetic dipole moments so I'd assume even in electrostatics we'd have magnetic fields; are they just assumed to cancel in electrostatics then?
 A: A stationary state of the system as a whole does not mean that the charges themselves are stationary. 
This is the case in standard magnetostatics: you have a current distribution that stays constant in time, even if each individual charge is moving, because there is another charge behind it to take its place.
Now, in quantum mechanics you need to be a good deal more careful, because the notion of trajectories is useless (and you cannot think of an atomic orbital as an ensemble of particles). Nevertheless, it is a perfectly well-formed question to ask "is there an electric current in this configuration?" even if you explicitly refrain from asking about the electron's trajectory, and if the orbital has a nonzero orbital angular momentum then the answer will be yes, even if the state itself is stationary.
In particular, it is perfectly consistent with a stationary solution of the Schrödinger equation to have a nonzero probability current: the continuity equation demands that the divergence of that current needs to vanish, but that still allows for the current, and its circulation and its magnetic dipole moment, to be nonzero. 
A: I don't think they necessarily cancel. It's just in electrostatics we choose to neglect these effects. In most cases the effects of the electrostatic fields are probably stronger than any effects of the intrinsic magnetic moments anyway.
Also, why do you think that stationary states cannot form magnetic fields?
