Answer:
Charge produces a field that acts on different charges. however action of this field appearance totally different from different reference frames.
By definition,
electric field are a few things that accelerates different charges, and
magnetic field are a few things that rotates different charges.
Consider charge at rest. It produces solely force field in its rest frame. during this frame it acts on different charges by fast them within the direction of the electrical field E. What we tend to see within the rest frame of the charge is that the momentum vectors of different charges during this frame are "boosted".
However, if we'll have a look at this from the moving frame, we'll see that momentum vectors of different charges don't seem to be simply "accelerated", however additionally "rotated".
