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.

History
In 1831, Heinrich Lenz, an Estonian physicist, for whom the symbol "L" of inductance is named, discovered the right-hand-rule relationship between a changing magnetic field and the direction of induced electric field, the non-Coulomb field.
