I have been wondering about a couple of things.
First, Faraday cages protect electronics within them from EMPs, right? So would the metal body of a car act as a Faraday cage and protect the electronics within the car?
And I was also wondering... there is a foil-lined envelope I can keep my credit card in to prevent a passerby with a special machine from stealing the info... I wondered if a similar envelope could protect my phone from being located all the time? And maybe that would also protect the phone from EMPs?
Note: I am not going anywhere that would be of legitimate interest to anyone, but I just don't like the idea that they have records of everywhere my phone goes.
I know, right? My problem is all the microwaves I use seem to be defective.
I use nothing but high-quality Reynolds Wrap aluminum foil, but these cheapie made in China microwave ovens seem to want to blow up all the time.
I just don’t understand it.
“I wondered if a similar envelope could protect my phone from being located all the time? And maybe that would also protect the phone from EMPs? “
Yes, it would protect your phone from being located, but it would also prevent you from receiving any calls or texts while the phone is in the bag.
As for protecting it from EMP, it probably would, but then again, if the cell towers are knocked out by EMP, the phone would be fairly useless. I supposed you would still have your photos though.
Also, do not have sex with Rabdom strangers.
Right, and doesn’t even actually need a continuous surface either for a simple cage, to protect against electric shock, for example. A connected surface might be more accurate, since you could have a surface with holes all over it, and the current would still preferentially flow on the outside of the surface, as long as it is connected so there is a path.
If you knew anything about science you would know that one of the problems with electric transmission is resistance in wire. It is called line losses. It is a problem in many fields. Also a wire passing through a magnetic field generates electricity. That is how motors and generators work. It is basic electricity.
Put your phone in an RF bag that you can buy on Amazon. Problem solved.
“Could disabling “Location” still make the phone trackable?”
Cell phone towers need to know who owns the device/phone connecting to the network to know if you are a subscriber. It is impossible to turn that off. Turning off “location” in your phone only turns it off for applications on the phone. The cell phone company still tracks your phone.
Shiny side out. Duh. Everyone knows that.

If you knew anything about science, you would know that power lines don’t move threw a magnetic field.
What are the odds an emp attack will be 'weapon of choice' for Putin? Your guess... And how prepared are we?

There is much confusion about Faraday shields, cages and electricity.
Faraday cages and shields are for EMF protection and do not require grounds. Cages (with holes) will allow threshold frequencies to pass. Example is the microwave viewing widow which let light pass but blocks microwave frequencies.
Protection from electricity requires that the person does not become a conductor. Birds can perch on powered HV lines.
A car is protection since the low resistance path is from a metal part to ground.
Thanks!
I should just say I don't know, because that question spans much more than Physics, EE, and military strategy.
In my wild guess opinion EMP attack would be a mistake for any foe of the US because EMP attack would not be as devastating as they are hyped to be, but would result in a full weapon-of-mass-destruction reply.
The reason I am relatively skeptical about EMP based on this analysis, especially the last few paragraphs.

Nevertheless, IMO we are making a mistake poking the bear. Sun Tsu wrote that you should build your enemy a golden bridge with which to withdraw. I think Hitler in his bunker would have fired any nukes he had, even if it meant extinction for Germany.
Second reason to let Putin escape is that things will get worse as we drive Putin into the arms of China, or destroy his regime to have the vacuum filled and weapons / technology / minerals / food sources be inherited by China.
“I just don’t understand it.”
maybe it’s chinese counterfeit Reynolds Wrap you’ve been using and genuine Renyolds Wrap would work ...
Silly person. Just use two layers- one layer shiny up and the other layer shiny down. That way your double secret internal sensor cannot send info out and “the MAN” cannot send info to your double secret sensor.
“Something about wanting the emp charge to be dissipated by being ‘caught’ in the chicken wire.”
Huh?
Everything you're saying has a strong ring of truth to it... Thanks for sharing. Oh, and I'll check out the link later... You're a wise person.
