An induced dipole occurs either randomly as a result of increased concentration of e- on one side of an atom/molecule or by the repulsion of said e- from another dipole. These molecules experience van der waals forces bc opposites attract.
An induced dipole results in randomly moving electrons in an atom suddenly accumulating on one side of an atom, resulting in a negative charge. This will "induce" a positive charge on one side of an adjacent atom, and hence result in an instantaneous dipole. This effect will cascade to adjacent atoms, and hence result in an intermolecular force.
Yes they induced dipoles are van der waals and can also be called other names like london forces. They work because they are like a domino effect that occurs due to a force of electrons being moved to one side or becoming denser.

I am pretty sure that induced dipole - induced dipole and Van der Waals forces are two names for the same thing.
