  Herbig Ae/Be stars are young, pre-main-sequence stars that sample the
transition in structure and evolution between low- and high-mass stars,
providing a key test of accretion processes in higher-mass stars. Few Herbig
Ae/Be stars have detected magnetic fields, calling into question whether the
magnetospheric accretion paradigm developed for low-mass stars can be scaled to
higher masses. We present He I 10830 \AA\ line profiles for 64 Herbig Ae/Be
stars with a magnetic field measurement in order to test magnetospheric
accretion in the physical regime where its efficacy remains uncertain. Of the 5
stars with a magnetic field detection, 1 shows redshifted absorption,
indicative of infall, and 2 show blueshifted absorption, tracing mass outflow.
The fraction of redshifted and blueshifted absorption profiles in the
non-magnetic Herbig Ae/Be stars is remarkably similar, suggesting that the
stellar magnetic field does not affect gas kinematics traced by He I 10830 \AA.
Line profile morphology does not correlate with the luminosity, rotation rate,
mass accretion rate, or disk inclination. Only the detection of a magnetic
field and a nearly face-on disk inclination show a correlation (albeit for few
sources). This provides further evidence for weaker dipoles and more complex
field topologies as stars develop a radiative envelope. The small number of
magnetic Herbig Ae/Be stars has already called into question whether
magnetospheric accretion can be scaled to higher masses; accretion signatures
are not substantially different in magnetic Herbig Ae/Be stars, casting further
doubt that they accrete in the same manner as classical T Tauri stars.
