  In this paper I will discuss new magnetic field diagnostics and
instrumentation for an area of astrophysics where magnetic field observations
have been difficult - circumstellar material. Such diagnostics would be
particularly relevant to star formation and evolution. Stellar photosphere
diagnostics include the Zeeman effect and atomic scattering diagnostics like
the Hanle Effect and atomic alignment. The Zeeman Effect is in general not
sensitive enough for the field strengths expected for circumstellar material,
and it is easily defeated by Doppler broadening in a dynamic envelope. Atomic
scattering diagnostics, pioneered recently for the Sun, are promising, but have
never been applied outside the Sun. For the study of unresolved envelopes, the
Hanle Effect may be applicable particularly in the ultraviolet. A medium
resolution UV spectropolarimeter, for instance, would serve for such studies.
Atomic alignment effects could utilize a ground-based, high signal-to-noise
spectropolarimeter, with profile information from high spectral resolution. I
will briefly mention several instrumentation development efforts in these
directions.
