  The local intrinsic parallel current density driven by electron drift wave
(DW) turbulence including electromagnetic (EM) effects is analytically studied.
The scalings of the ratios of intrinsic current density driven by residual
turbulent flux and by turbulent source to the bootstrap current density with
electron density and temperature are predicted to be $T_e^{3/4}T_i/n_e$ and
$T_eT_i/n_e$, respectively. Based on the typical parameters in DIII-D pedestal
region, the local intrinsic current density driven by both the residual
turbulent flux and the turbulent source is negligible. However, despite the
negligible turbulent source driven current, the residual turbulent flux driven
local intrinsic current density by EM DW turbulence can reach about 66% of the
bootstrap current density for ITER pedestal parameters due to much lower
collisionality in ITER than in DIII-D. Moreover, the contributions from
adiabatic ES parts, non-adiabatic ES parts and non-adiabatic EM parts of the
plasma response to electromagnetic fluctuations are analyzed. It is found that
there exists strong cancelation between non-adiabatic ES response and the
non-adiabatic EM response for the ITER pedestal case, and thus the kinetic
stress contributed by the adiabatic ES response of parallel electron pressure
dominates the intrinsic current drive. This is different from the ES electron
DW case. Therefore, the EM effects on turbulence driven intrinsic current
density should be carefully considered in the future reactor with high ratio of
electron pressure to the magnetic pressure and steep pressure profile.
