A new image reveals magnetic fields around our galaxy's central black hole

magnetic field, a vector field in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to line up in the direction of the field. Magnetic fields force moving electrically charged particles in a circular or helical path. This force—exerted on electric currents in wires in a magnetic field—underlies the operation of electric motors. (For more information about magnetic fields, see magnetism. Around a permanent magnet or a wire carrying a steady electric current in one direction, the ...(100 of 476 words)
