Here's the deal:

Simple form: The amount of electricity produced is proportional to the rate of change in magnetism. The amount of magnetism produced is proportional to the rate of change in electricity.

Complete form: Look up Maxwell's equations.

If you have a wire loop (the more wires and the more loops, the better) moving past a magnet, or if you have the magnet move past the coil, you get electricity produced in the wire, because the magnetic field strength changes as things move. The hamster turns the cage, which rotates the generator, which moves something past something else, and the change in magnetic field strength inside the coil makes the electricity.

To get more power:

Bigger magnets
More wire
Faster rotation

Home >All Categories > Science & Mathematics >Engineering >Open Question Roygbiv Member since:April 24, 2010Total points:131 (Level 1)I need a schematic for a simple sawtooth synthesizer. I am making an oscilloscope from a discarded CRT tube. I have none of the circuitry, but I can get it to display the electron beam, all I need is a sawtooth wave synth SCHEMATIC that can put out about 3 volts or so. It needs to have a wide frequency range, but no gates or super complex schematics. Prefferably transistor based, but 555 is ok too. Nothing too complex please.Answer Question
