Talk:Magnetometer screening

Merge with metal detector? Billlion 09:17, 23 May 2006 (UTC)

• Neither article is really right in my mind. Metal detector is slanted towards finding metals in the ground. There is no article that really address the pure technology which should be under Magnetometer but it is not. This is the only article that covers other uses besides finding coins or mines in the ground, it woould not be easy to add to metal detector without being lost. Having said that, I see no problem with taking these articles and rearranging them. Before creating this article, I asked on the talk page for Magnetometer if anyone could provide something and there were no takers. A possible plan would be expand the Magnetometer article to include much of the technoligy that is in the metal detector article, assuming that this is the same technoligy. Then redo metal detector to cover all uses for metals detection. Vegaswikian 16:52, 23 May 2006 (UTC)

I don't think magnetometer is the right place either. A magnetometer measures the magnetic field. A metal detector detects high conductivity objects by inducing eddy currents and thus changing the mutual inductance between two coils. This is often thought of as detecting a 'secondary' magnetic field created by the eddy currents all though that is not strictly what happens, just a convenient fiction that helps one to understand it. I think the right thing to do is have an article at metal detector that explains how they work, something briefly about their uses, history, and then move the detail about the applications to other (new) articles.Billlion 17:51, 23 May 2006 (UTC)

I think that would work. Do you know enough about the topic to do the work? Vegaswikian 17:56, 23 May 2006 (UTC)

Well I am in the process of learning! I work on the mathematics of a kind of scanning metal detector but I am not an expert on the electronics. I think the best thing is to try and if anything I write offends a real expert they can try to fix it!Billlion 09:36, 24 May 2006 (UTC)
