all rather awkward and it's difficult to find a good description of them. Some type of form for entering references would be nice. One could always require more sources but setting the standard requirements to high will just prevent people from making useful additions. A few of my sources are links to webpages of research groups that seem bona fide. People who find that the sources aren't good enough should be welcome to add more sources and to remove sources that become unnecessary by their additions. Errors and doubtful unsupported information need removal of course. Not having a sample list of magnetic field values (or only the Earth's magnetic field) is a larger shortcoming than not having done the job of a major review article.

I have given sources, what's wrong with them? Most are links to other Wiki articles. Shouldn't it be possible to refer to other Wiki articles assuming that they have done their job of finding reliable sources? Unfortunately Wiki has several different standards for including references and they are

Please administrators, consider seriously eliminating the reference to pseudovectors in the heading of the article. It is unnecessarily misleading. Otherwise move it to the last element of the article as a marginal comment.

The animation titled "The Amperian loop model" is incorrect on the right side. The poles should be moving left-right. The magnetic field should look like the graphic immediately above titled "The magnetic pole model".

OK, I see that now, thanks! I am used to seeing two poles of opposite sign moving closer together to produce a dipole source, and associated dipole field.
