I recently received the following question regarding EMP effects: “What will happen to vehicles with electronic ignitions, a Chevy with an ignition module, but they are not hooked to a battery, with no path for electricity to follow, can it do damage? There may not be power on the grid, but what about a generator? I work on commercial air conditioners which on occasions, have rather violent electrical explosions from thyristors carrying 480vac. There are control boards in close proximity, less than 1 foot, that are heavily populated with semiconductors which survive just fine.

While a sheet of aluminum separate the two, it’s far from a faraday cage. With my degree in electronic engineering technology, I find it hard to believe components off line or in vehicles would automatically ‘fry’. There must be a difference of potential and a completed circuit in order for that to happen. “components off line or in vehicles would automatically ‘fry’”The word “automatically” is incorrect in that there are many factors which will determine the electromagnetic field strength, the transient voltages and induced currents that result.The ‘fry’ won’t be automatic, some electronics will fry while others could theoretically survive. Devices could survive if properly shielded (Faraday) or far enough way from the source due to the inverse-square law versus source energy and location.Your example of an air conditioner electrical explosion which did not harm the control boards of the system might not consist of the same characteristics of a purposed EMP weapon and its “Compton effect”. There is lots of information that can be sourced from Google (or your search engine of choice) which covers the topic.

It’s worth spending some time on, and preparing for what could be our next Pearl Harbor. @Matt in Oklahoma,A best way is to use a potable RF Spectrum Analyzer (inside Faraday cage) together with a RF transmitting source (outside Faraday cage). Various comparative measurements are made (at various frequencies) in order to determine the attenuation (dB) effectiveness of said Faraday cage.

It’s not simple (one needs to understand electronic measurement techniques, RF energy, and so on). Additionally the test equipment is not cheapCell phone frequencies are in the vicinity of 800 MHz. EMP pulse is going to be broad band to an extent, so there’s more to it. @KenI agree with you and understand.I guess what I’m saying is the regular folks can’t test it correctly but if they use the radios, cells etc and it fails then it will certainly fail in a hard broad EMP event.I’m pretty sure that if all it takes is cardboard and a trash can or a microwave then we wouldn’t have been digging 2ft in frozen German ground to bury our batteries. I’ve even seen plastic bags advertising protection which is laughable because static electricity is nowhere near the intensity.

The amount of false information out there is crazy.We all also know the variables are too great for certainties especially with the development of directional EMP weapons or those who live closer to ground zero like Nebraska in comparison to the west side of the Rockies in a singular high altitude detonation which I also very much doubt given that anyone who has 1 weapon probably has many more unless it’s a rouge small group. Any other international attack will have multiple locations with simultaneous strikes.I was also just seeing if anyone knew of a better test for the community.

Compton effects are gamma interaction with matter, a nuclear interaction in which the gamma hits an electron results in energy transferring from the photon gamma to electrons in its path scattering the photon and it losing part of its energy to the electron the photon energy hits. This effect does not create an electrical current but charged electrons.

The concern being that these charged electrons will destroy circuits designed for current which is moving electrons. Compton is only ONE type of interaction with matter from nuclear blasts.

Nuclear detection instruments of radiation is designed to find and measure these charged electrons. We call these charged electrons beta radiation. They are particles by nature and NOT electrical current. Gamma has the ionizing impact travel as electromagnetic energy or photon. All discussions seem to cross these two up badly. EMP is an outcome of massive nuclear interactions that follows the blast path and burst. Remarks an EMP can wipe out larger areas and take out the USA etc.

Than the nuclear blast damage is really not physically going to happen. The electrical damage is just that blast impact moment. The nuclear damage has long term impacts.

So please keep the rhetoric down. People need information not fiction. The energies of the nuclear blast also do not equate to the electrical magnetic pulse. The nuclear energies are known and constant emissions from their sources. These values again are not electrical charges. The above article isnt quite correct. The EMP is a moving magnetic pulse.

A wire loop in a varying magnetic field will create a potential (voltage) in the wire. Thats how a motor works, a series of wire loops are spun in a magnetic field.

The bigger the loop, or the more turns in the loop, the greater the energy generated in the loop.The power grid is susceptible to EMP because it is composed of very long wires (many miles long) which basically form huge wire loops. As the EMP travels across these huge power grid loops, gigantic currents can be generated which can burn out transformers. A high enough current will melt the wire in the transmission line itself.

For a brief moment before teh grid burns out, there can be huge voltages on the lines that may damage any electrical/electronics connected to the grid.At the other end, the electronics in your computer is very small but still contains many of these “loops”. Inside an integrated circuit chip (IC), there are loops within the semiconductor material between the various transistors, resistors, etc.

Etched into the material. These are very small loops, but semiconductor material is sensitive. A strong EMP will burn out an IC.

The EMP created when a thyristor blows, or when a person touches and “shocks” a device, can be enough to damage poorly designed electronics.Within a car, air conditioner, etc., there are similar loops called “ground loops”. Grounds are not all equal even when they are close to each other. The earth, wires, the metal of a car, the metal of an air conditioner case, are not resistance free. The resistance between grounds is small, but given a large voltage or current, it is enough to create a loop and damage the system. A lot of effort goes into electronics and systems to have single point grounds (one ground only) to minimize ground loops.In general, a solar flare/CME is fairly weak but huge in size, that puts the power grid in jeopardy but not ground based electronics that are not connected to the power grid (unplugged or are turned off). An EMP from a nuclear weapon is so strong that all electrical and electronic systems near the blast are in danger. A Faraday cage is appropriate for a nuclear weapon EMP, probably not required for a CME/flare.

I’m quite familiar with the Compton Event and its effects. These “loops” do exist but any external pulse, noise, emp, whatever would have a gauntlet of sheet metal enclosures to navigate as they are already well shielded from ambient ignition noise. Since this event has never happened this is all speculation and conjecture. Any shielding in addition to is always a good idea but to what extent it’s required, no one knows. If there’s anyone else here with a degree in electronics, worked in the semiconductor business for 23 years and is now an electrical engineer in an R&D lab that would like to have a battle of wits with an bunch of unarmed people, ring out!.

I think you are correct. There must be a small length of wire acting as an antenna that the EMP will induce current through to be carried to an otherwise shielded device. HOWEVER, directly exposed semiconductors (especially CMOS type) not even wired up can be FRIED by an EMP, and it does not have to be a big one, either.

A friend of mine had a bag of ICs (CMOS timers) next to a power cable for a welder and the cable generated enough induced EM Waves that he cooked the WHOLE BAG of them! ($80 down the toilet). Our business is inside of a SOLID Steel building that is very well grounded and the sheets are bonded, so the high voltage has to be carried into the building by wires that breech the walls. We investigated the best way to protect out computer servers inside and we ended up with a “Double DC” system to protect them. We replaced all A/C PS units in the computers with Mobile DC supplies, and supply them with batteries, and the batteries are supplied with charger/supplies, and all of them goes through 2 sets of quick acting fuses. We do have two small skylights that we ordered Phosphor-bronze screen to cover, but have not yet installed it (got to get off my butt and do it).

You CAN protect things. I see a lot of emphisis addressing an EMP attack of sort on known electonics but fail to see much discussion on “Radio Frequency weapons and the Infrastructure”. In 1977, Lt General Robert L. Schweitzel, US Army retired, gave a statement to the Joint Economic Committee addressing these issues.

A couple points I want to make. One the Electromagnetic wave will induce a high voltage on any metal object it hits.

That voltage is normally bled off of any object that is grounded. Any object that is not grounded will not bleed off (like your car) but may act like a Capaciter and hold that charge. I wonder how many people will die by opening their car door and providing a path to ground for that energy.

I plan to ground out any metal after an EMP strike. Keep in mind that old style TV’s would hold enough charge to kill you even after being turned off for a month.I believe that EMP’s will be a much used battlefield strategy in the coming years.

It is only a matter of time till we are hit as our enemies will want to remove our electronic helpers from any conflict. So after the emp strike don’t assume there won’t be any more. There may well be dozens as our enemies try to take out any hardened electronics or any kept in faraday cages.

Everybody is thinking hard how he can protect our household equipment.I see it as resolving the symptoms and not the cause.How much simpler would it be when we spent our efforts to take away the cause of the problem. Why are we waiting to put the elite in a Faraday cage. And throw the keys in a deep ocean.Those crooks who have willingly used everything that they could to lead this world into devastation. They murdered millions of people. Started two world wars and are poking bear Russia to start an other one.Why is Hillary not in jail, why is Obama not in jail, why is the FED still in operation We know who the crooks are, we know what they did. What are we waiting for?We are all frogs in water that is heating up slowly while nothing is done That is our biggest mistake!!Do not wait for a government organization who is going to solve your problems. That will never happen as the government is the problem.WE, THE PEOPLE, HAVE TO CLEAN THE MESS IN OUR COUNTRY BECAUSE IT IS OUR COUNTRY!

IT IS HIGH TIME TO WAKE UP!. Mind you, it’s global, not isolated to USA. I’m Canadian, worrying just as much about the elites’ WWW3, and EMP killing infrastructure. Difference is, my survival plan invokes looting medicine, food delivery trucks, weapons, and holding a strategic position near my city of roughly 1 million (near Toronto), so when fools are looting fried electronics and grocery stores, I’ll have all I and my people need.

Including fresh water and wild game, seeds, shelter, etc. Let the unprepared mass kill each other off, watch from a distance, stand guard, prepare defence via high school and university chemistry stores.

Remember, trucks full of canned goods will sit at warehouses. Masses are stupid, ignorant. Avoid them at all costs. Know the land around you.

Use train tracks to get around. I’m not by any means an authority on Electricity or EMP.

But I do have a question about the question as to if something was not plugged in will it be affected. Two thoughts come to mind. For something to be shorted out doesn’t it have to be plugged in so that current and ground have a complete circuit. So if an appliance is not plugged into ground how then can it be affected. Just because you have current would not seem to mean a given appliance will be dead if it were not grounded. Setting aside all the caveats previously talked about.

For example in a operational wire feed welder you cannot weld anything, even though the welder is running if the object you are welding is not sufficiently grounded, because current no matter the amount does not have a complete path. Which brings a new thought in cars if you were to install a battery disconnect switch to disconnect the negative terminal on the battery and any other associated grounds to curcuits when not in operation, thereby removing the complete circuit path to auto electronics wouldn’t a car survive.

So long as it was not in operation when an EMP occurred and the battery ground and circuitgrounds were disconnected. Things are as Johnny Cash said “Going by the book”. America is the thorn on the side of the globalists and has to be removed. We are the.mystery babylon. that will fall. 9/11 might have been that already as it predicted an attack on.mystery babylon.

that will fall within an hour which the twin towers did and we have been a former shell ever since led by globalists. Bush caved into his Daddy’s demands and buddied with the global elites and are friends with Obama/Clintons the trio circle.There is nothing Trump can do or should do. I suspect he will be murdered as they think Hillary will win but law states that Vice President Mike Pence will replace Trump if he is unable to complete his duty.either dead or arrested. Today’s generation either doesn’t know the law or are lying thru their teeth.

Put a liner of cardboard in the can. Leave what you want to protect in their boxes.

Wrap the boxes in foil ensuring there are no gaps. Wrap that in construction paper, and then foil again. Make sure the cans seals tightly and cover the seams with conductive tape.If so inclined and want a better chance of your gear surviving, wrap the can in heavy/multiple layers of wrapping paper and then wrap it all up in copper mesh. Keep it in your basement or an interior room/closet.That’s the best construction method I have read.Old school all metal bird/animal cages/pens may work as well. Just makes sure you gear is not touching exposed metal of the cage and follow the same wrapping method.

I put a small radio in a Christmas tin lined with cardboard, turned on the radio and sealed it up. Note that I sanded the rim and lid to ensure a good connection for my faraday gage.

I could still hear the radio suggesting to me that radio waves were penetrating my faraday cage. I then made a second, larger cage and placed the first cage inside. I could still hear the radio.

It took three embedded cages to eliminate all radio reception. I haven’t tried a metal trash can but it seems prudent to do so before trusting it as a faraday cage.
