Calculating Magnetic field dimensions

Click For Summary

Discussion Overview

The discussion revolves around calculating the range of a magnetic field produced by a permanent magnet, specifically a cube-shaped N35 Neodymium magnet with dimensions of 10mm x 10mm. Participants explore resources and tools available for this calculation.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant inquires about the equations needed to calculate the magnetic field range of a specific permanent magnet.
  • Another participant provides a link to an online field calculator for both round and rectangular magnets, indicating that they do not know where to find the equations.
  • A later reply confirms that the online calculator works for their needs.
  • Additional information is shared about a free iPhone app from the same company that can assist with these calculations.

Areas of Agreement / Disagreement

Participants generally agree on the usefulness of the provided online resources and tools, but there is no consensus on the specific equations for calculating the magnetic field range.

Contextual Notes

Limitations include the lack of detailed equations or theoretical background in the discussion, as well as the dependency on the specific dimensions and composition of the magnet.

Who May Find This Useful

Individuals interested in magnetism, engineering applications, or those needing to calculate magnetic fields for specific magnet configurations.

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
 
Physics news on Phys.org
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.

works perfectly for my purposes thanks a lot
 
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.
