When a charge is at movement it creates an induced field, if that charge it is also accelerating it will create also a radiated EM field caused by the acceleration, the induced field is proportional to 1/distance^2 while the radiated field is just proportional to 1/distance, that is the reason the first one is also called the "near field" while the second one is called "far field", for more information about this topic you can look the Lienard-Wiechert potentials:


I was wondering if given the fields E and B at a point and its space and time derivatives we can figure out the induced and radiated components of the field at that point. Does anybody know if this can be done? I have been looking for it but I have not found anything.
