What affects the size of the magnetic moment of a diatomic molecule?

Without the full quantum mechanical treatment let's look at an atom. In all atoms, the electrons are in motion, and are creating magnetic fields around their paths of travel. And each electron is in a specific orbital (Fermi energy level) and will have an associated angular momentum unique to that specific orbital. To discover the atomic (magnetic) dipole moment, we have to gather up and add the spins of each of the electrons, and also find and sum each orbital angular momentum where an electron is operating. With the spins of the electrons and the angular momenta of the orbitals, we can then combine those to discover the total angular momentum. From there, it's a hop, skip and a jump to find the magnitude of the atom's dipole moment. In a molecule, we have to do this for multiple atoms. Additionally we have to make accommodations for the magnetic moments of any unpaired electrons. We must also account for nuclear spin configuration and the energy state of the molecule to arrive at the magnitude of the magnetic moment. We might have to consider nuclear magnetism in the isotopes of some elements, but these are the basic variables that must be managed to find the magnitude of the magnetic moment of a molecule. A link can be found below to check facts and review the mathematics involved.

How does the molecular order structure explain the magnetic properties of oxygen?
Molecular orbital theory predicts that ground state diatomic oxygen has two unpaired electrons (it is a diradical) which occupy its pi orbitals. These unpaired electrons produce a magnetic moment and are responsible for the paramagnetic property of diatomic oxygen.
Why is the magnetic moment of a nucleus smaller than the magnetic moment of an electron?
Because the charge/mass ratio of a nucleus is smaller than the charge/mass ratio of an electron
What is the dipole moment for CCI4?
It is a symmetrical tetrahedral molecule so has zero dipole moment.
Dipole moment vector of water molecule?
dipole moment of water is 1.85 Debye
What are Magnetic Properties of Metals?
Iron (Fe) Cobalt (Co) and Nickel (Ni) iron, steel, nickel, and cobalt all have magnetic properties. Lodestone is also magnetic and was used to make early compasses a long time ago because it has magnetic metal elements in it.

Is the magnetic moment of gas an extensive property or intensive property?
Each atom and molecule will have its own magnetic moment - thus making it an intensive property. If you get a collection of such atoms or molecules in a gas, the total combined magnetic moments will be an extensive property.
Is magnetic moment scalar or vector?
Magnetic moment is a vecotr quantity
Why carbon monoxide is polar?
CO is a diatomic linear molecule C=O, both these atoms have about '1.0' difference of electronegativities so it is in the range of polarity and it has a certain value of Dipole moment.
Two identical magnets of magnetic moment are joined What will be the resultant magnetic moment?
The resultant magnetic moment is dependent on the orientation in which the identical magnets were joined. If they are joined in opposite direction, the net magnetic moment will go to zero.
Why is magnitude of an electron spin greater than its magnetic moment?
The Spin magnetic moment i approximately the same as the angular magnetic dipole moment. What then do you men by grater magnitude?
Can effective magnetic moment be calculated from negative mass magnetic susceptibility ie diamagnetic substances?
Yes, the magnetic moment can be calculated from the diamagnetic substances.
What is the zeeman effect?
The Zeeman effect is the splitting of single spectral lines into three or more in the presence of a magnetic field.
A steel wire of length l has a magnetic moment M It is then bent into a semi circular arc The new magnetic moment is?
Since, a steel wire is bent into a semi circular arc ,the new magnetic moment will be M
Does sulfur have a magnetic property?
The element does have a magnetic moment. This is because there is one pair of electrons and two individual electron molecules in the valence shell. This is to say that the unpaired electron molecules create a magnetic moment. That is sulfur's magnetic property.
What molecule has zero dipole moment?
Carbon dioxide has a zero dipole moment. The C=O bonds are polar, but because the molecule is linear, the polarities cancel one another and the molecule has a zero dipole moment. Click on the related link for an illustration of the carbon dioxide molecule showing its dipole moment.
Why nucles contributes less magnetic moment than electron magnetic moment due to spin?
Because it is about 10,000 times smaller. The magnetic moment depends on the strength of a magnet's poles, and on its separation; or, in the case of a current loop, the strength of the current, and the area it surrounds.
