Q:
The motion of electron is judged by the frame of reference. So, does electric & magnetic fields depend on fro where we feel it ?

A:

In Special Relativity, the fields don't depend on your location but they do depend on your state of motion. There are well-defined rules for calculating the electric and magnetic fields in one frame from the fields in another frame, given the relative velocity of the frames. The electric field in one frame depends on both the electric and magnetic fields in the other frame, and so does the magnetic field.
