Sure, thanks, but I was referring to a similar device like the ones in the article based on superconductivity,not meta-materials, thanks.

Recently a device invisible to a static magnetic field was described. The device features a cylinder with two concentric layers. While the inner layer consists of a superconducting material that repels magnetic fields, the outer layer is a ferromagnetic material that attracts them. Placed in a...

well i did this experiments in liquid one magnet fixed one magnetized micro-particle turns out v= constant/r fits my data exactly

Look what I am asking is very simple, I think many think in complected terms so forget about the theory or textbook questions for a minute, do you agree if you have 2 magnets they will attract each other and move toward each other (nobody mentioned monopoles) if their opposite poles face each...

thanks but the response does not answer the question and is wrong check the following: http://geophysics.ou.edu/solid_earth/notes/mag_basic/mag_basic.html as you know if you keep on magnet fixed and you have another magnet some distance apart they attract if their poles are opposite...

So if we can one large not moving magnet and a small magnet that is attracted to the large magnet we know that ( http://en.wikipedia.org/wiki/Magnet ) F = μ qm1 qm2 /(4 pi r^2). Here the small magnet is traveling in a straight line because it is attracted by the large magnet. Where F is...

thanks guys so what would be some simple recommended readings to understand this better? or even online classes? for example it is easy in my mind to understand gravitation as curved space time. However, I have a hard time picturing this. Also, everything I read says that photons are the force...

It seems to me that nobody can answer the question. there is no shame in a simple "I don't know". First, qed and modern physics states that the force carriers for em force are photons. So photons should be observable. If there are not there that means that they do not carry that force. So no...

I understand that as one person here puts it "The electromagnetic interaction is mediated by the constant exchange of photons from one charged object to another. Some electromagnetic interactions involve "real" photons or "virtual" photons instead." But suppose I have 2 magnets and push...
