An induced dipole moment occurs when there is movement in the electrons of a bond otherwise known as polarization that creates fleeting unbalanced distributions of electrons and thus small dipole moments, whereas in a regular dipole moment the sharing of electrons at all times is unbalanced due to one of the two bonded atoms having a significantly stronger electronegativity.
Dipole dipole interactions are between dipoles on two polar molecules. Conversely, dipole-induced-dipole interactions can occur between a polar and a nonpolar molecule. The polar molecule induces a dipole by approaching the nonpolar molecule and shifting the electrons. Take for example, the interaction between HCl (has a dipole moment) and Ar (nonpolar, no dipole moment). As the Cl gets closer to Ar, the electrons in Ar shift away from Cl because Cl has higher electron density. This shifting in electrons is an induced dipole.
