What happens to the magnetic field of a star that collapses to become a black hole?
A- The magnetic field becomes infinitely intensified.
B-the magnetic field is radiated away black holes never have magnetic fields
C-the magnetic field becomes compressed and intensified by a factor equal to the ratio of the stars orgiginal diameter to the diameter of the even horizon.
D-the magnetic field becomes weaker by the ratio of the diameter of the black hole even horizon to the stars original diameter.
