Black holes can generate strong magnetic fields through the acceleration of matter in the form of jets, which are composed of protons and electrons. According to Rita Sambruna from NASA's Goddard Space Flight Center, these jets, which travel at near light speed, create magnetic fields similar to those found in quasars and neutron stars. The exact composition of these jets remains debated, but recent evidence suggests they primarily consist of protons. Further research is essential to fully understand the mechanisms behind black hole jets and their magnetic fields.
PREREQUISITESAstronomers, astrophysicists, and students interested in black hole research and the dynamics of cosmic jets will benefit from this discussion.
However, it is not clear why these jets generate a magnetic field since we are not sure of what exactly they are made of. Further:"Black hole jets are one of the great paradoxes in astronomy," said Rita Sambruna of NASA's Goddard Space Flight Center, Greenbelt, Md. "How is it that black holes, so efficient at pulling matter in, can also accelerate matter away at near light speed? We still don't know how these jets form, but at least we now have a solid idea about what they're made of."
So if these near light speed jets of protons are zooming out both ends of the black hole axis, they generate a magnetic field similar to quasars and neutron stars. But what's inside the black hole to generate this protons, positron stream? Much more study is needed to better understand this galactic phenomenon, since it seems most if not all galaxies have some super massive black hole in their centers. Another interesting NewScientist.com article: http://space.newscientist.com/artic...k-hole-the-ultimate-particle-accelerator.html , which says the black hole's magnetic field is a giant particle accelerator. Hope this helps.The composition of black hole jets has been the topic of heated debate for several decades. Scientists generally agree that the jets must be made either of electrons and their antimatter partners, called positrons, or an even mix of electrons and protons. Recent theoretical and observational advances have pointed in the direction of the latter. The Swift data provides the most compelling evidence to date that the jets must have protons.
