I have been working on a generator. I would like to double check the "guidelines" given to me. I need to calculate the magnetic field density and stregnth at given distance away from the magnet surface (pole). I also need to calculate B as they decay to the side.(adsbygoogle = window.adsbygoogle || []).push({});

I have circular magnets on a 1/4" steel disk. They are N48 grade, 1" in diameter, and 1/4 " thick. They are placed at 30 degree intervals around a circle. I need to insure that my diameter is appropriate such that the flux between the magnets at any given diameter of the disk is appropriate. I will also need to know what the flux is at a given distance away from the pole of the magnet.

I would appreciate it if any formulas are provided, that you tell me how you got it.
