Black holes: The ultimate abyss 2/6

Good question. Magnetism can be a result of Gravity. For example. The core of earth is thought to be a mass of molten metals rotating and moving around caused by gravity. Without the Gravity earths core would be not move. If earths core was still, there would be no magnetic field around to protect us. So gravity is necessary for earth to have a magnetic field. It is possible if a black hole had a high metal ratio it could exert strong magnetic forces. I could be wrong though.

The way I see it... magnetism is just gravity... in the same way that a black hole captures matter and rotates it in a centrifugal manner, magnetism caused by electron flow in a wire is essentially a bunch of these back holes stacked on top of each other... i.e. the electrons travelling through a wire have mass that have a gravitational effect observed as magentism... then again I have no idea why this gravitational effect only has significant effect only on metallic objects.

Well...maybe if one is moving close to the speed of light relative to the other? :)
