What is the cause for diamagnetism and other types of magnetism?
Is it related to Farady's law or quantum mechanical properties of matter?

Diamagnetism is a type of magnetism exhibited by certain materials in which the material itself does not possess a magnetic field, but is temporarily induced to create one in the presence of an external magnetic field. This is in contrast to ferromagnetism and paramagnetism, which involve the inherent magnetic properties of the material itself.
The cause of diamagnetism is the orbital motion of electrons within an atom. When an external magnetic field is applied, the electrons in the atoms of a diamagnetic material will experience a force that causes them to move in a direction opposite to the field. This creates a tiny magnetic field that opposes the external field, resulting in a repulsive force between the material and the magnet.
Diamagnetic materials will align themselves in a direction opposite to the applied magnetic field, causing them to be repelled by the magnet. This effect is very weak and only temporary, as the material will lose its magnetism once the external field is removed.
Yes, all materials have some degree of diamagnetic properties. However, the effect is very weak in most materials and is often overshadowed by other types of magnetism, such as ferromagnetism or paramagnetism.
Diamagnetism is not commonly used in everyday life, as its effects are very weak. However, it is used in scientific research to study the properties of materials and in medical imaging techniques such as magnetic resonance imaging (MRI).
