>What's the reason on an atomic or subatomic level, what is creating that field ?

maxwell described electrical behavior mathematecaly but in this case is better to go with the father of electrical engineering charles steinmetz, from his book "Elementary Lectures on Electric Discharges, Waves and Impulses, and Other Transients":

"a condutor subject to an electric potential will produce two simultaneous and complementary fields, one magnetic concentric to the conductor and the other electrostatic (or better called dielectric) radial to the conductor"

on a atomic level the electric potential applied to the conductor basically puts all the atoms and their respective electro-magnetic fields in phase with each other creating a coherent field all through the conductor.

this is why any conductor in a high speed circuit (in other words, working at high frequencies) becomes automatically an antenna (its inherent) and this is why you have to take special precautions for high speed circuits and their design.
