We report on electromagnetic (EM) coupling of multi-filament helically wound superconducting tapes in the steady state under a constantly ramped magnetic field. Especially, we focus on the dependence of EM coupling upon the round core radius R. In the case of large R, EM coupling is well approximated by an analysis for a flat tape. Meanwhile, for small R, EM response of a helical conductor might be close to that for a tubular superconductor.
