Hi PF Pros... I wonder if you can help me...(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to see if there is a formula for how fast magnets attract. I know that there is the inverse square in terms of power loss and that magnetism is a field that travels at or near light speed.

But, for example, if I have 2 cyllander NIB magnets (.5" wide x 1" long) with 5,000 Gauss each and they are 3 inches away from each other... at what speed will they meet? If I have the speed I can calculate the time/distance. (as for weight or other forces like friction, etc, please feel free to make something up for the equation).

Thanks!
