Im just old
That's pretty cool, thanks for sharing this.
Man, even as a little child I was always fascinated by magnets. Hasn't subsided even one little bit over the years. Gyroscopes as well. Find me a gyroscope made out of magnetic components and I would probably quit playing Borderlands 2 for at least a day or three.

This is a way-cool expiriment.
Forget whether it's logistically possible or not, all I can envision is a 10 story copper pipe, with magnetic snowboards to jump down into. Fun would be had.

That's how most generators work. A magnet spinning in a coil of copper wire, or vice-versa, a coil of copper wire spinning in a magnet. Most of the time both are coils of wire and the magnetism comes from putting an electrical current through one. If a magnet moves past a wire or a wire moves past a magnet it induces a current in the wire. Make that wire a complete circuit and you have electron flow. The amount of current is dependent on several things, but the more windings of wire that are passing through the magnetic field the more current you get. In the US our power's frequency is mainly 60 Hertz, which is related to the speed of the rotor. It's not always like that, some generators regulate the frequency after that so it stays constant, they would be the ones you should use with frequency and voltage sensitive tools like computers. Some are a little more complicated than that to make clean power.
I see a heck of a lot of generators at work, we sell them and I've repaired them for years. This was a little simplified and they are manufactured several different ways but I just wanted to give people a little info for generator buying. After that it's all about matching up your wattage.

P.S for gotta do it nerds: You can check it out on a small scale if you have a decent multimeter, a magnet, and a piece of wire. Moving the magnet back-and-forth across the wire will induce a small current in the wire which can be read with the meter's amperage setting if it can read a very low amperage. You could even put the leads of the meter together and use that as your wire. You made power!

Not to mention that we are all living within a huge magnetic and electrical field created by the spinning earth. I've often wondered if the electrical currents in the human body were induced by being passed through this magnetic field that surrounds us. And what would happen if that magnetic field ceased.
Speaking of magnetism, this account is a rather interesting, if controversial, use of magnetic properties: http://en.wikipedia.org/wiki/Philadelphia_Experiment

That got me thinking, Rich. What if there was something in low earth orbit that acted as a conductor and the Earth's magnetic field could induce a current in that conductor? I wonder what kind of power you would get and if it could be used.
I don't know how you would do something like that, though. Maybe you could spray some kind of metal in the atmosphere? Like from planes or something?
I rode a submarine for about four years. Submarines are periodically "depermed" or "degaussed". From moving through the water the hull gets a magnetic pattern. We docked in a special pier in the middle of the harbor and wrapped the boat in heavy cables, the whole boat. They had some crazy big electrical stuff on those piers, and a not very nice barracks for the crew. A current was put through the cables to change the pattern. Every time I see something about the Philadelphia thing I think of that.
