 I came here because I was confused about this too. Specifically, I tried to look up Magnetic Dipole and it redirected to the Magnetic Moment article. There is a sub-category "Magnetic Dipole" on this page but for someone who doesn't know what a Dipole is (me), that really should be linked somewhere in that section. I didn't think of looking up dipole until I came here to the Talk page and saw this discussion. Also, the section on the page that talks about Magnetic Dipoles includes a link to the wikipedia entry on Magnetic Dipoles... which links back to this article. So, self referencing links are not very helpful. I'm going to go ahead and edit the Magnetic Dipole section of this page to link to the Dipole page. Makes sense to me. I don't edit often so feel free to change it back or something if you really disagree, but I can't imagine having the page reference itself is more helpful.  21:20, 11 July 2011
