Stigmashaped (“s” shaped with sharp corners), paired, transmitter antennae were excited at various radio frequencies. Clear attractive forces were observed to propel all antenna pairs, one towards the other. However, no selfforces of the type predicted by the relativistic Lorentz force law were seen for all the antennae standing alone, even though these forces were expected to be considerably bigger than the observed forces between different antennae. The positive results on the one hand and the null results on the other may imply that the relativistic Lorentz force is not applicable to currents in physically open circuits, and that the nonrelativistic cardinal force law of Ampère is correct for all cases.

Keywords: stigma antenna, electrodynamic forces, law of electrodynamics of Ampère, cardinal law, law of BiotSavart, Grassmann, relativistic Lorentz force, forces between currents, forces between incomplete circuits, open circuits, forces, radioexcited antennae, forces, electromagnetic selfforces, (non) equivalence of Ampère and Lorentz force law, relativistic forces, Maxwell hypothesis of displacement current, continuity
