Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I am new to the forum, thus please be patient with me.

I have a little bit of a problem....

Currently working with magnets. Basically, I need to derive an equation for the attractive/repulsive force between two magnets given a distance between them. The most important thing is that these magnets not interfere with eachother, in other words I need the attractive/repulsive force to be zero.

Thoughts so far....

- Newton's Universal Gravity equation

- F = GMm/R²

- manipulate the pull force of the magnet to derive a mass...divide pull force of magnet by 9.8m/s^2

- need to set F to an infinitely small amount and solve for R

I do not get offended very easily, so if you need to completely slam my thoughts so far in order to get me on the right track, I understand.

Thank you in advance for your help
