Where are real electric dipoles ?

  1. Nov 3, 2008 #1
    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.
