AI Thread Summary
Mylar is an insulator with a metallic coating, which can potentially block radio signals when used to wrap a laptop. However, it is unlikely to affect the magnetic properties of the computer or its hard drive, as hard drives are not magnetized in a way that would be influenced by Mylar. The discussion also mentions a subjective experience of the laptop feeling lighter after being wrapped in Mylar, but this is not scientifically substantiated. Overall, Mylar's properties suggest it would primarily serve as a barrier to radio signals without impacting the laptop's functionality. The thread emphasizes the need for more engagement in physics discussions online.

Mylar is an insulator, but it is coated with metal. Intuitively it should be possible to wrap a laptop in mylar and insulate the laptop from radio signals... but is there any chance it might affect magnetically the computer and/or its hard drive? I mean a very loose airy wrapping, like in packaging, not a tight wrapping like in gift boxes. After all, we do have capacitors made of mylar...

[Incidentally, I did wrap the laptop in mylar for a while after a wi fi-induced BSOD, and I had briefly (?) the impression that it went lighter! But of course it was subjective...]

There's no need to be snide. Threads sometimes fall through the cracks without being answered.

I doubt the mylar would have any effect on your computer's hard drive since it isn't magnetized.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...

Thread 'Why measure the speed of light in one direction?'

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
