In a sourceless and loseless region an EM wave is propagating with an Electric field represented by E = y(hat) [5e^(-jkx)] V/M.
In which Cartesian direction is this EM wave traveling?
I know the answer is +x direction..
However, I'm curious as to why this is. In a sourceless region, there would be no current, correct? Because there is no charge, therefore no current, and therefore no magnetic field?
Correct me if I'm wrong, but a charge has to be in motion for an electric field to produce a magnetic field, right?
So if there's no charge, and no B-field due to a static E - field.. how does an Electromagnetic wave exist, and how does it travel in the +X direction?
From my understanding, an EM wave is produced by succession of induced electric and magnetic fields.
Any help would be great!
