electic generator Answered

I have not made this yet, but my idea is building an electric generator using a bicycle wheel surrounded by a non turning metal frame. Tightly backed on the bicycle wheel would be permanent magnets arranged in a slant pointing in the same diection and outward toward the surrounding frame. On the frame would again be permanent magnets wrapped with copper wire slanting inward toward the bicycle wheel. The magnets facing each other would have like poles. North facing north or south facing south. I know this is just like an electric motor so far. You would get the electricity from the arrangement by placing a thin copper stip on the top of the frame. But different from the motor is the idea that like poles repel. once you gave the wheel a slight movement in the same direction that the magnets slant the wheel would turn until the magnetic energy would exhaust. You could make strong magnets using rebar wrapped in copper wire and use a inverter to change the AC in your house to DC and connect the current to the copper wire surrounding the rebar. Then when the magnetism of the rebar is sufficiently strong cut the rebar using a hack saw into small pieces to place in either the bicycle wheel or metal frame surrounding the wheel, I'm not sure of the electric power dynamics you could produce, but it would seem that using strong enough magnets could make a generator that could power as large a device with amperage/volts you can create. It might be used as a device to run your furnace blower or refrigerator in an emergency if the power produced was high enough. I think this would all depend on the strength of the magnets you produce. But if it works-you could have electric power from the magnets as an alternative to batteries or gas driven generators.

You people are all so negative with your physics, me and my freind were designing a magnetic bike, we never got around to building. I still think it can work.

Thinking is good. So is research. This idea comes up every 20 years or so (the first time in the late middle ages or early renaissance, at a german king's court). The problem that you aren't seeing is that the magnets don't stop attracting-they slow down the wheel as much as they speed it up. Tipping the magnet doesn't change this. At least come up with some unique reason for it to work-like neodinium(sp?) magnets or 'magnetic shielding' that is timed in a counter-rotation to emphasize only the attractive properties of magnatism. (BTW, you can use that last bit, but only if I get 5% of the investment income, off the top, for 'continuing research' so that when you get to court the lawyers can't take it back ; ) )

Go ahead and build it! While It may not work, I'm sure you will learn quite a bit in the process. If Ben Franklin had accepted what everyone knew as fact, "lightning is retribution from God," he would have never invented the lightning rod.

magnetic energy Please tell me more about this new found energy! I don't think magnets work that way.

Look up "perpetual motion machine", "the first law of thermodynamics" and "conservation of energy" before building this. L
