What Is Dipole Moment?
An electric dipole moment describes the separation of positive and negative charge within a system, such as a polar molecule. It is important in chemistry and electromagnetism for understanding molecular polarity and behavior in electric fields.
The Formula
p = q × d, where q is the magnitude of each (equal and opposite) charge and d is the distance separating them. The SI unit is the coulomb-meter (C·m), though the debye (D) is commonly used for molecular dipoles, where 1 D ≈ 3.33564 × 10⁻³⁰ C·m.
