Lorentz Field

The Lorentz field is an electric field created at a specific point inside a material when electric dipoles—pairs of positive and negative charges separated by a small distance—are present. Imagine many tiny dipoles stretched throughout a material; their individual fields combine to produce an average or "local" field at a point. The Lorentz field accounts for the influence of all nearby dipoles, including the polarization of the surrounding medium, providing a more accurate measure of the microscopic electric environment than just considering a single dipole alone. It's important in understanding how materials respond to electric fields at the atomic level.
