Non-Coulomb Electric Field
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.
Non-Constant Current
Polarized Metal Bar and Steady State
A metal bar moving through a magnetic field will polarize as a result of magnetic force, and the resulting charge separation, maintained by the magnetic force, is reminiscent of a battery. The polarized bar can then be used to generate an electric current in a circuit.
Additionally, as a result of the polarization, an electric field is also generated.

A Mathematical Model
Along a closed path, the general equation for the non-Coulomb electric field is [math]\displaystyle{ emf = \textstyle\int\limits_{i}^{f} \vec{E}_{NC} \cdot \Delta \vec{l} \frac{1}{4 \pi \epsilon_0 }Q(\frac{1}{r_2} - \frac{1}{r_3}) }[/math]
What are the mathematical equations that allow us to model this topic. For example [math]\displaystyle{ {\frac{d\vec{p}}{dt}}_{system} = \vec{F}_{net} }[/math] where p is the momentum of the system and F is the net force from the surroundings.
