                            Description
                                    Making emphasis on observations that have included some type of
polarization analysis, I concentrate on two subjects. First, the vector
magnetic field configuration of structures with different sizes is
reviewed. I cover from magnetic knots, and their relation to small scale
magnetic elements, to large sunspots. In doing so, a different concept
of how a pore should be described is proposed. Second, the fibril
organization of the magnetic field in penumbrae is reviewed. Both, field
strength and inclination fluctuations in the azimuthal direction are
seen. The necessary gas pressure fluctuations needed to achieve force
balance are analyzed. As a solution to the missing Evershed flow
problem, the findings of a return flux surrounding sunspots by
Westendorp et al. (1997b) are considered.
