Transcript. Dipole-dipole forces occur between molecules with permanent dipoles (i.e., polar molecules). For molecules of similar size and mass, the strength of these forces increases with increasing polarity. Polar molecules can also induce dipoles in nonpolar molecules, resulting in dipole–induced dipole forces. Created by Sal Khan.

Most dipoles will require a little "trimming or adding" to resonate at the desired frequency. Here is a good recommendation in 7 steps. 1.
