Multiple Choice
The jets associated with AGN are defined by intense magnetic fields. What is the origin of these magnetic fields?
A) The stars that formed the black hole had magnetic fields, and the black hole retains those fields.
B) The accretion disk contains a plasma of charged particles. The acceleration of these particles produces a magnetic field.
C) The intense gravity of the black hole attracts and concentrates the magnetic field associated with the host galaxy as a whole.
D) Friction between the inner and outer parts of the rotating accretion disk produce the magnetic fields.
