RE: [Vo]:The principle of the mutual energy

For what it’s worth, my recollection is that the 1/r loss applies to an infinite linear antenna. Thus it’s only an approximation for a real antenna. As for evanescent waves, I have not seen a measurement of their speed of initiation relative to the distance to the source that generates them.

Re: [Vo]:Watch a Powerful Electromagnet Shrink a Quarter to Half Its Size

I don't think so. Electric fencers are relatively high voltage at 10Hz AC. They are limited to very low current so you don't kill what touches it. The 10Hz AC is very painful. On Wed, Jul 20, 2016 at 5:47 PM, Jack Cole wrote: > I thought this was very interesting. I

[Vo]:Watch a Powerful Electromagnet Shrink a Quarter to Half Its Size

I thought this was very interesting. I wonder what would happen to a loaded electrolytic cathode or TiH2. "Shrinking a quarter down to half its size sounds like a magic trick, but there’s nothing magic about this experiment highlighted by Physics Girl

That's interesting! It is sort of complicated, like Rube Goldberg machine. But so is a hybrid automobile. Sometimes complicated things work. - Jed

Re: [Vo]:The principle of the mutual energy

Robin, It is my experience that the coupling falls off as 1/r to the third power at large distances. Dave -Original Message- From: mixent To: vortex-l Sent: Wed, Jul 20, 2016 12:04 am Subject: Re: [Vo]:The principle of the mutual

Re: [Vo]:The principle of the mutual energy

That is correct. It even goes to 1/4th power at longer distances. The coil are separated on air core RF transformers to increase the Q of the coils. This leads to better selectivity/ tuning. The coupling does go down. -Original Message- From: David Roberson

Re: [Vo]:The principle of the mutual energy

I may be remembering wrong, but I believe that the evanescent magnetic field strength falls off as 1/r^3 and the coupled evanescent power falls off as 1/r^6. For the propagating field, the strength of the magnetic field falls off as 1/r in free space and the coupled power falls off as 1/r^2. In
