Claimed by Geoffrey McKelvey, Work in Progress

The non-Coulomb electric field, often represented by the variable [math]\displaystyle{ \vec{E}_{NC} }[/math], is an electric field, which does not result from a stationary point charge.

Magnetic Field- Induced Electric Field

The concept of the non-Coulomb electric field arises from the discovery of electric fields, which cannot be created as a result of Coulomb's law. There are two primary examples in which we see this field, in a wire, with non-constant current & in a bar moving through and being polarized by an external magnetic field. Due to the involvement of motion, the resulting potential difference is often referred to as motional emf.

A Mathematical Model

Along a closed path, the general equation for the non-Coulomb electric field is [math]\displaystyle{ |emf| = \oint \vec{E}_{NC} \cdot \Delta \vec{l} = |\frac{d\Phi_{mag}}{dt}| }[/math]
