Distance to which magnets start attracting each other

[Daniel3AL]

Hi, I was wondering whether it was posible with a formula to measure the distance to which two equal magnets start attracting to each other. I was looking at this web page https://www.kjmagnetics.com/blog.asp?p=surface-fields-101 and I am not sure if this is the right formula.

I have two Neodymium Magnets N52 with a radius of 0.5" and a length of 1.5". I am looking for a formula because I need to order more magnets and I need to know this before I order more. Thanks

Any help or comment is appreciated.

Daniel

They always interact regardless of the distance, although thte strength gets weaker with distance. Whether they attract or repulse each other depends on their orientation.
