Hi! I'm new here. I took physics back when we calculated pterodactyl drag and I remember what an integral looks like but that's about it. I hope I chose the right prefix.
What I'd like to do is find the dimensions of N48 neodymium cylinder magnets that would produce a minimum field strength of 0.25 Gauss 4 feet (48") from the center of a line connecting 2 magnets 22 inches apart. The magnets would both have the N pole facing up and the poles are on the ends of the cylinders.
I also need to know how much moving both magnets 2" apart and 2" closer would affect the field strength at 4 feet.
Is there a free computer program, website or spreadsheet that could calculate this or give me a graph of lengths and diameters that would work?
I'm sure some of you know the answer off the top of your head so feel free to chime in. :)
Thanks.
