Where are real electric dipoles ?

[rogerharris]

I'm trying to understand what electric dipoles, quadrupoles etc are.



If i look for definitions of electric dipoles, they are given as pairs of point charges, yet no real examples are given..

"A point charge is an idealized model of a particle which has an electric charge. A point charge is an electric charge at a mathematical point with no dimensions"

So i can understand this better, does anybody know of any real or natural examples where electric dipoles exist ?

A water molecule is an electric dipole. In fact, if it were not, water would be a gas at room temperature.

Ok thanks for reminder. Thats a good start.
