Basic AC Generator, question on magnetic field?

Question

Ok i am building a basic ac generator for class (IE a wire loop spinning in a magnetic field) and need to know what factors to look at in magnets (Strength, distance apart etc) and whats more important to consider.

Please help and if possible include sources

Answer 1

It is pretty simple, more turns in the coil, smaller distance, stronger magnets and faster speed all generate more electricity.

Answer 2

Well, i would suggest you put the wire loop in the static part of the generator and make the magnet turn. You can use a static magnet to get a little ac current. I would advice you use the strongest magnet you can get so you need less wire turns. Now it all will depend on if you want a big current or a big voltage. With big voltage you need more turns and with more current but less voltage use less turns.

Hope this helps.
