Some magnetic structures on scales of hundreds of parsecs revealed by Faraday rotation at high Galactic latitude have been associated with intermediate-velocity (IV) gas. The interaction of IV gas with its magnetized surroundings is an important part of dynamo processes that build up large-scale magnetic fields in galaxies. Nowhere can this interaction be observed in more detail than in the local interstellar medium. After a brief introduction, I will present new results for a nearby IV filament using observations of polarization of diffuse Galactic synchrotron emission from the GALFACTS survey, made with the 300-m Arecibo radio telescope. These data reveal a complicated magnetic structure that is related to the distribution and kinematics of the neutral gas and plasma.
