Calculating Magnetic field dimensions

  • #1
simple question which probably has a complex answer, if given the dimensions and composition or a permanent magnet ie if the magnet is a cube 10mm x 10mm N35 Neodymium where would one find the equation to calculate the range at which the magnet extended

Here is an online field calculator for both round and rectangular magnets.

There are others on the web. I don't know of where to find the equations.

Just a freebie, since you mentioned my employer. Arnold also has an app for that. If you're on an iPhone, you can go to the App Store and get a free iPhone app that does that, too.
