I actually did not realize of this response until now.
First what does that have to do with this thread WE ALL KNOW that the speed of light varies negligible in diferent materials. Usually ALL the speeds at which light travels is considered the speed of light it is still light right?. The maximun speed is what most refers too when talking about it. EMW moves at the speed of light as a general term or you want me to analyze the speed of all the materials known to man and state them here. You want to look very intelligent but have said nothing new to add here. What information? is the magnetic wave modulated somehow what are you talking about???. You mean the colors produced by a prism?. Wave Information must contain intermittent variations in at least two states. What??? the peak of the wave travel faster than C in vacuum? Where did you copy that from can you provide a reference. I am really shocked at this responses. I want to know where have you gotten this info.

ATTRACTION that is the meaning of this thread WE ALL KNOW that the magnetic field permeates but the poles has to be alined a certain way to produce attraction (Two things trying to stick together). Did you read the OP's post???

If the Alternate current changes faster than the atoms can tranfer their charge you could theoretically charge a battery with AC. Off coarse this was given as a metaphor. I was trying to make it simple to understand for the OP.

Proof of what? are you saying that EMW attract metals? That was the main thread question, You know...
Maxwell equations were proved through experimentation by Hertz in 1887. The four equations actually prove that there are no isolated magnetic poles. There is an electric field and an electric charge. That electric fields are produced by changing magnetic fields and that there are circulated magnetic fieds produced. Still does not offer any ATTRACTION prove. Please elaborate more on that I am interested.

You got close on this one "This is a property of any wave propagating as an ever-expanding closed surface, as it is inherent in the geometry"> (of space time) was missing, this is what I am stiking too. The rest of you parragraph I feel is WRONG go study Black and white holes and you will see it like the moderm physics community.
Looks like some one just told you to come and prove me wrong and THIS IS A CHILDISH thing and serve no purpose here.

Wrong again, is with with metals you know... what about the energy content in the photons, the speed of light varies with the density of the medium. What about the Infrared portion of the spectrum and the heat it carries. An EMW interact a trillion of different ways with metals. Open your mind. So you belive everything written on books eh? Why don't you use your own judgement and use your brain and STOP repeating what you read. Just repeating to everyone what others said, prove them wrong be a leader not a follower. Make your own observations and experiments and make your own conclusions. You are confusing magnetic waves with electric waves.

Particle Coliders works on particles colisions not Waves, PC magnetic fields don't make the particles run faster than the MAXIMUN speed of light.

It is not good what you have done here, anyone with a little common sense can realize that you are just bending my comments to acomodate yours just to prove me wrong that is NOT HONORABLE nor ETHICAL and serve a bad and confusing purpose to the OP. I suggest just you to stop doing this kind of stuff unless you have something to add that is related to the meaning of this Thread. Please Stop your smears tactics and Ad hominem tactics.
Mr. Silencer please don't take this as a personal attact but I feel you know about this subject a lot maybe more than me but I don't know why you want to prove me wrong in things you well know I am not.
We have by no means learned everything about electomagnetic energy, which encompasses radio and TV signals, heat, light, and even Gamma rays, we just scrached the surface.
