Good evening. Can anyone explain me the origin of the electric field in the F-N-L's law ?
I'm referring to this one :

[itex]\int_l \vec E^* d\vec l =-\int_s \frac{\partial \vec B}{\partial t} d\vec S[/itex]

where [itex]\vec E^*[/itex] is defined as (i'm reporting the words of the book) :
[itex]\vec E - \vec v \times \vec B[/itex].

in particular what is [itex]\vec E[/itex] and what is its origin.

//I apologize for any syntax/grammar error, I have to improve my English, I'm Italian.

It's the intensity of the electric field.


[itex]E[/itex][itex]=[/itex][itex]\frac{F}{q}[/itex],
where F is the force, which the field acts on the electric charge


Intensity of the electric field is used to characterize the electric field.

do you want to know where the E field comes from in faradays law or how E is related to B in that equation.
