Talk:Electromagnetic shielding

message: I would like to see some of the physics behind this concept, instead of a general "this is the definition of shielding." - eykanal
It would also be a very good idea to quickly explain what "coupling" means. - Raeyin
RF shielding doesn't really cover anything that's specific to the field of RF.  It should be merged here for now. — Omegatron 15:44, 23 March 2006 (UTC)

message: I myself am a student, and I and others find Wikepedia a very useful research site. I generally however find it useful to have dictionary.com running aswell! This is because of the complex scientific language used throughout the site. I myself am in my top Science set at school and am gifted and talented, however I think this particular article definitely needs a bit of translation. Some people are probably put off by the very first sentance! For I think it doesn't really explain simply to begin. The detail is supposed to be added later on in the aticle.
Please do not hate me for this comment, as said I and my fellow students really enjoy this site!  —Preceding unsigned comment added by 81.178.73.198 (talk) 17:28, 17 January 2009 (UTC)

message: Are there any materials that shield magnetism but are not themselves attracted to magnets?Ratsbew (talk) 16:59, 12 April 2009 (UTC)
replies: text: In generating stations, isolated-phase bus cancels the magnetic field produced by heavy currents by enclosing the generator leads in an aluminum tube; currents induced in the tube creat a field that nearly cancels the field produced by the current in the generator lead. But in the static case, unless you can inject a current from some other source to cancel the field, anything you use for shielding is going to have to have a higher permeability than air, and so, will stick to a magnet. --Wtshymanski (talk) 14:37, 17 February 2012 (UTC)

message: https://en.wikipedia.org/wiki/Tempest_(codename)
TEMPEST is a National Security Agency specification and a NATO certification [1][2] referring to spying on information systems through leaking emanations, including unintentional radio or electrical signals, sounds, and vibrations.[3] TEMPEST covers both methods to spy upon others >>> and how to shield equipment against such spying <<<. The protection efforts are also known as emission security (EMSEC), which is a subset of communications security (COMSEC).[4]  — Preceding unsigned comment added by 173.81.169.7 (talk) 20:31, 15 April 2018 (UTC)

message: In the mathematical model section the mathematical model is postulated as Ho*Vector(z)=H_r*Vector(r) - H_rho*Vector(theta)
If that would be the case then How would it work if theta was 90 degrees or pi/2 ? the component that has to be used is rho axis vector (as in rho=r*sin(theta)) (cylindrical coordinates) (rho=sqrt(x^2+y^2)).
z is not part of the spherical coordinates system but of cartesian and cylindrical. you cannot do Vector(r)-Vector(theta) and expect to have Vector(z). Ctmv (talk) 14:43, 2 September 2023 (UTC)
