[edit] From PNA/Physics

The equation has the units Amp-turns per centimeter, but the definition has the units Amps per meter. It looks like it should be Amp-turns per meter. (198.118.127.182 20:30, 8 June 2006 (UTC)C. Raeihle, 6/8/06)

The Gauss (unit) article says "one ampere per meter is ten thousand oersted". This article says "One oersted equals 1000/4π, or 79.58 ampere-turns per meter". They can't both be right.

[edit] Visual Ambiguity!

The forward-slash (division), italic captial I and lowercase l all look identical in the default font in Opera 9! Perhaps all the equations should be put in math mode.

[edit] Examples

It would be good to give an example or two to illustrate the magnitude of the unit in terms that are physically meaningful for the lay reader. For example: "on a typical jet engine ... while in a typical electric toothbrush ...". —DIV (128.250.80.15 (talk) 09:44, 19 April 2008 (UTC))

Okay, "jet engine" is probably a very bad example ...which is why I'm not editing the article. —DIV (128.250.80.15 (talk) 09:46, 19 April 2008 (UTC))
A good starting point would be the examples given in the introduction to the "Watt" article. —DIV (128.250.80.15 (talk) 02:45, 8 May 2008 (UTC))
In the article orders of magnitude (magnetic flux density) there are examples given in Tesla, so these can be converted into Oersted for this article. I'm currently too lazy to do it myself... However, maybe the link is enough because otherwise the information would be doubled. --Cyfal (talk) 05:05, 8 May 2008 (UTC)
