Black holes absorb everything that falls into them, including photons of light and heat. So what does it mean to ask, what temperature are black holes?

Now, supermassive black holes can shine with the energy of billions of stars, when they become quasars. When they’re actively feeding on stars and clouds of gas and dust. This material piles up into an accretion disk around the black hole with such density that it acts like the core of a star, undergoing nuclear fusion.

Is it possible that a black hole is a point of magnetism?

Gravity is the weakest at the center of the earth and the strongest at the very edge.

A point of magnetism is the strongest at the point and the weakest at the very edge.

Does any of the material go into the black hole or does all of it only go as far as the accretion disk?

Is it possible that at the inside of the accretion disk is the weakest gravity and past that point is the weakest magnetism creating the difference?

Less massive, higher temperatures.

As far as temperature, I really have no understanding of it, only the less movement the colder and the more movement the hotter. Is that right?
