Our polarization measurements of near - infrared point sources indicate a well - ordered global magnetic field that is perpendicular to the main filament, implying that the magnetic field is likely to have controlled the formation of the main filament. (arxiv.org)
Reader Bruce Merchant speculated that Mars would need a protective global magnetic field to sustain a life - friendly environment. (sciencenews.org)
The resultant weak global magnetic field and the constant bombardment of stellar wind would serve to intensify losses of atmosphere on the star - facing side.» (sciencedaily.com)
