WebWhen we say something is polar, it has a very specific meaning. It means that there is a spatial separation of charges, or a dipole moment. In the simplest case, this is given by: μ = Q r Where μ is the dipole moment, Q is the charge on each pole (equal and opposite) and r is the distance between the charges.
