WebWhen you place a molecule with an electric dipole in an electric field, a force acts to turn the molecule so that the positive and negative ends line up with the field. The magnitude of the turning force is given by the formula µ = q × d where q is the amount of charge and d is the distance between the two charges. µ is the turning moment.
