If Magnetism is the result of moving charge, then why aren't all Atoms magnetic if they're surrounded by a moving cloud of negative charge?

They are, atoms have a magnetic dipole moment, from both the spin of the electrons, the orbital angular momentum of the electrons, and the nucleus itself. However, when you have many atoms, the magnetic moments aren't necessarily aligned and if they're all pointing different directions then the magnetic fields cancel out. Only special materials have the magnetic moments align naturally.
