| Abstract: | In this paper, the electromagnetic field, generated by an electric dipole of uniform straight line of arbitrary direction, is calculated using the Lorentz transformation of the relativity formulas are also proved by calculating the electromagnetic field of two point charges of uniform motion in a theory. The motion in a straight line. The distribution of the electromagnetic field is discussed and simulated when the electric dipole moves in some special direction . |
