Magnetic force and distance

[tropes]

Thanks guys
I finally hit the correct link and plugged in some actual numbers. I have two Neo42 disc magnets each D= .75", length= .5" and Distance apart is 1.25". Now the calculator says the pull= 70.9!!
Now I say bullshit. I can hold these two magnets one on each side of my hand and there is not 70 lbs of pull. Great calculator but the results are questionable or I did something wrong.

Okay, I went back and tried again. Now I get 0 lbs. pull and 0 lbs of repulsion.

Try the IMS Trading calculator as suggested. A lot more advanced.

Here is a calculation on your magnet setup.

Why does the flux density increase when the magnets get further apart?

Maybe flux density is not what I think it is? what does this graph say?

As the magnets get further apart, then the flux density increases?

What does this mean?
