What is the cause for diamagnetism and other types of magnetism?

Click For Summary
SUMMARY

The causes of diamagnetism, paramagnetism, and ferromagnetism are rooted in the quantum mechanical properties of matter, particularly the intrinsic angular momentum (spin) and orbital angular momentum of electrons. Each electron contributes to a magnetic dipole moment, and the total magnetic moment of an atom is determined by the sum of these effects. Additionally, the bonding between atoms in a solid influences their magnetic dipole response to external magnetic fields. Understanding these interactions is essential for identifying the magnetic properties of materials.

What is the cause for diamagnetism and other types of magnetism?

Is it related to Farady's law or quantum mechanical properties of matter?
 
Physics news on Phys.org


So how do identify easily that a molecule or atom is diamagnetic or paramagnetic or ferromagnetic?
 


It's actually more complex than two sentences on physics forums can do justice to the subject. Each electron has intrinsic angular momentum (spin) which gives rise to a magnetic dipole moment, and orbital angular momentum depending on what state it is in inside the atom, which also gives rise to a magnetic moment. Add up all the magnetic effects of all the electrons in an atom and you can get a total magnetic moment. But you also have to take into consideration how the atoms bond with each to form a solid, because will effect their magnetic dipole's ability to respond to an applied field. Also, in responding to an applied magnetic field, the electron states change, which change their magnetic properties.
