Magnetic force and distance

[tropes]

Good links but none of these links answers the question," What is the attraction and repulsion force of 2 given size magnets at a given distance?"
For example: I have two Neo 40 disc magnets attracting each other 1 inch apart. The surface area of each magnet is 11/14 square inch. The magnets are 1" in diameter and 1/8" thick.

Hi Peter,

I found this link: http://www.magnetsales.com/Design/DesignG.htm

And this: http://www.magnetsales.com/Design/Tools1.htm and this: http://www.magnetsales.com/Design/Calc_filles/PullAndPushBetween2DiscMagnets.asp

I understand the calculations are approximations.  Use material N39H for N40 to approximate it ( no N40 material is included...)

Thanks Gyula
Good calculator at magnetsales.com. The answer is given in " gauss at X" . How do I convert that to lbs.?

It looks like the "push" and "pull" numbers below the "guass at X" are the forces in pounds.

Hi Peter,

At this link I included in my previous post  http://www.magnetsales.com/Design/Calc_filles/PullAndPushBetween2DiscMagnets.asp you get not only Gauss at X but the attract and repel force in Pounds so you do not need to convert.  (By the way they have a conversion help here: http://www.magnetsales.com/Design/Tools1.htm#units )
