How are induced dipoles formed?

Basically, electrons in an atom fluctuate over time and in one instant electrons may accumulate on one part of a molecule making side of the molecule more negative and leaving the other side more positive, becoming, therefore, an instantaneous dipole. An instantaneous dipole moment on one molecule will distort the electron cloud on a neighboring molecule giving rise to a dipole moment on the other molecule. The two instantaneous dipoles will then attract each other (induced dipole-induced dipole intermolecular forces).

Adding on, this phenomenon is also known as Van der Waals Force. This takes place in every single molecular relationship such as hydrogen and dipole-ionic.

An induced dipole is when a (partial) positive or negative charge is brought near a nonpolar molecule and disturbs the arrangement of electrons in the nonpolar species. The electrons in this nonpolar species develop a dipole (one side has more electrons than another), so it is called an induced dipole because the dipole was induced by another charged atom/molecule.

In short, an induced dipole is when a nonpolar molecule binds with a polar molecule as the dipoles attract it.

Electrons, by chance, can clump in a particular section of an atom, forming partial negative and positive charges. These charges can cause electrons in nearby atoms to move around and clump together. Therefore, the dipole is "induced" by another atom's charge distribution.

Are there other forms of dipoles?

Electrons randomly distribute around a nucleus continuously. By that logic there are moments when there are more electrons concentrated in one area than another which creates a slightly uneven charge distribution which will cause a momentary dipole at one instantaneous second.
