==Abstract==

The original cardinal law of Ampere for the force between two current elements is not Lorentz covariant.&nbsp; This classical electrodynamic law of Ampere yields the same result as the relativistic Lorentz law when both are integrated around closed circuits.&nbsp; To distinguish the non-covariant cardinal force law of Ampere and the relativistic Lorentz force law one may examine the force between open circuits excited by high frequency high power alternating current.&nbsp; A straight wire antenna and a Z-shaped wire antenna were chosen.&nbsp; They were excited at 108 Mhz with 50 watts, 147 Mhz with 150 watts, and 2450 Mhz with 500 watts.&nbsp; It was observed for the first time that such antennas attract each other or arrange themselves to be perpendicular to each other.&nbsp; No self torque was observed; although the self forces predicted were expected to be considerably larger than the mutual forces between two separate antennas.&nbsp; The positive results on the one hand, revealing the forces between two antennas, directly proves the exclusive validity of the non-covariant cardinal Ampere force law; while the null results on the other hand, revealing no self torque on the Z-antenna, directly disproves the relativistic force for open circuits.
