Surprisingly strong magnetic fields challenge black holes' pull

A new study of supermassive black holes at the centers of galaxies has found magnetic fields play an impressive role in the systems' dynamics. In fact, in dozens of black holes surveyed, the magnetic field strength matched the force produced by the black holes' powerful gravitational pull, says a team of scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory and Max Planck Institute for Radio Astronomy (MPIfR) in Bonn, Germany. The findings are published in this we...
