So I have this huge solid cylinder of aluminum about a foot tall, and 2-3 inches in diameter. I understand that aluminum is not a permanent magnet. But it DOES conduct electricity. So, if I wrapped a conductor around it, and hooked that up to a power source, would the aluminum become an electromagnet? I'm guessing yes? How well of a magnet would it be compared to an equally sized cylinder of iron? Also, if so, what are some ways to increase the strength of the magnet? The idea is to wrap wire around it as many times as possible, I know that. But what about current and voltage? Will the strength increase if I increase either of those? I don't think I have much control over current, though. Using a thicker wire, would help too, decreasing resistance, right? This isn't going to induce a huge magnetic field right? I don't want to attract everything metal in the room toward myself.
