Can someone help explain dipole moments a little more

Dipole moment is a quantity that describes two opposite charges separated by some distance. It is the product of the magnitude of the separated charge and the distance of separation.

Dipole moments occur when there is a large difference in electronegativity between the atoms. The more electronegative atom is said to have a partial negative charge and the less electronegative atom will have a partial positive charge. The arrow that signifies a dipole moment is drawn from the partial positive pointing to the partial negative which shows the strong electron pulling power the partial negative atom will have. If the dipole moments cancel, meaning they go in opposite directions, the molecule is nonpolar. For all other molecules with dipole moments that do not cancel, the molecule will be polar.

To add on to the other responses, there will be a stronger dipole moment when there is a greater electronegative difference between the two atoms.
