But it's well known that black holes can have magnetic fields. IIRC, there've even been some recent proposals which use the black hole's magnetic field to explain how energy can be transferred from the black hole to its accretion disk.
I wonder which is more preposterous, Mitra on black holes or Pat Boone on evolution?
If the collapse object is source for the energy sustaining the intense magnetic field, then the object isn’t ‘black’ in Stephen’s sense of using that term.
