Black holes are cool. Unfortunately, there is none nearby, which makes their observation tricky. In particular, obtaining experimental confirmation of Hawking's radiation is completely out of reach for now.
So I had this idea of creating a small one in my garage. Basically you 'only' need to get a bunch of matter to a sufficient density so that the gravity overcomes all repulsive forces. But that's an incredible amount of pressure. A hydraulic press would seem like a gentle tickle in comparison. So I was thinking of using some huge electromagnets in order to concentrate some electrically charged matter in a single point. But before starting the actual construction, I would like to estimate how much powering these electromagnets would affect my electricity bill.
I have another issue I need to take care of. Once my tiny black hole is created, then nothing can get out of it. In particular, it won't be able to exchange gamma photons with the electromagnets. Does that mean it won't be affected by their magnetic field any more? If that's the case, how can I stabilize it? Because if I don't, there is a risk that it will just be attracted by the Earth's gravity and start a journey to the center of the Earth, engulfing everything on its way? And if that happens, how long before it swallows the whole planet?
