Homework Statement
the electric field and the magnetic field are not disjoint. what may seem as an electric field to an observer stationary relative to a charge, is perceived as a magnetic field to another observer who is not stationary relative to said charge. however, there is conservation between the two because in reality, they are one and the same physical phenomenon.
* we can easily calculate the electric field due to a line of static charges, given the overall charge.
* we can also easily calculate the magnetic field due a line of moving charges given the current.
Q: Wouldn't a line of moving charges also produce 'some' non-zero electric field?

Maxwell
The Attempt at a Solution
It seems awkward to me that as soon as the charges start to move, imagine the lowest possible electron drift speed, *all* of the electric field drops to 0 and is represented only as the magnetic field. My assumption would be, the greater the current, less 'electric field' produced, and the more 'magnetic field' it would produce.
I know that "the magnetic field produced by stationary charges" = 0, by definition of current. However, is the opposite also true? Namely, "the electric field produced by a line of moving charge" ? Is it always 0, or is it dependent on the current, electron drift speed, or other factor?
