I‘m building a low RPM generator and seen many DYI projects videos online.I have noticed they mostly use rectangular earth magnets.and use coils that are winded in a rectangular coil shapeI have ROUND earth magnets. Should I wind my coils in a circle shape instead of rectangular shape?I‘m assuming that having the coil match the shape of magnet means a more even magnetic pull on the coil. Am I correct in thinking this?I guess my basic question is, before I wind all these coils, what shape should I wind my coils when using ROUND earth magnets. Circular or rectangular? Thanks in advance!
It can be found in any nursery along with the small bags of fertilizer or try K-Mart, Walmart although they might have there garden stuff put away.

buy two neodymium magnets from internet . buy 22 AWG copper wire for motor winding . make a coil of wire . takeout the two end and connect it to small bulb or LED. (-)- bulb ! ! [ !!!!!! ] m [ !!!!!! ] magnets [ !!!!!! ] [ !!!!!! ] ^ coil
Magnetic force strength falls as the square of the distance. Closest winding shape is better.
For best effect, the coil is would on a form made of iron or some other magnetic material. The coil should follow the shape of that form. The shape of the form is determined by the geometry of the generator or motor, as you want to get the soil as close to the magnets as possible. No, the coil need not match the shape of the permanent magnet. You can wind them in whatever shape fits the geometry of the motor, and the forms they are wound on.
