Q&A for How to Make a Faraday Cage

So long as the containers are conductive and can seal properly, those should work pretty well. These would be able to protect small electronics such as cell phones and the like.

You can, but you are then speaking about mothballing a car because all of the sensitive electronic components need protected. You may wish to look at a bicycle motor if you are mechanically inclined, or perhaps an old, old car or surplus jeep: no electronics. A Model T replica, or an actual, maybe a Willy's or something. Heck a golf cart with a lawn mower engine might be what you like best, or you might just be better off with a horse or a good mule because they can thread their way through the throngs of cars that were turned into boulders. Best wishes either way!

Yes, any conductive metal will work. Silver is the best choice, but very expensive.

You would have to disconnect the generator completely and make sure no cables are outside of the cage, then take a large metal trash can and coat the inside with plastic. There is no need to wrap the generator in plastic as long as there are layers of plastic and metal completely encasing it from the outside. It must be completely airtight to avoid empty exposure.

Yes. The key is that it is sturdy enough, if your conductive material punches a hole through your insulating layer you will be making an antenna instead. Remember that most devices run on micro volts and an EMP can subject these to thousands of volts in load equivalent amperage.

Your car does not act as a Faraday cage. It does not block signals.

For a large scale object like that, it might be best to build a sort of structure or cube using a brass or bronze screening or mesh. Build it using 2x4s for the frame, then staple the mesh around all sides and along the bottom. Alternating layers with plastic sheathing between mesh would even be better but the plastic would not allow airflow, so obviously you wouldn't want to run fuel burning generator inside of it for very long, as it would kill you if you were to be overcome by the fumes.

That depends on what you mean by "use it". You might be able to successfully operate the on/off button but the capacitive touch screen will not work while appropriately wrapped and the sound would be seriously muffled at best.

No, it won't cause a capacitor is also an electronic device and it won't store any induced current from an EMP. So, it will be fried too.

Yes, because you would have turned something made of wood into something made with something metal.

If you can ensure that is is airtight and doesn't have any leaks or exposed metal, yes.

The same as the instructions above. Wrap it in a plastic bag, then wrap it with foil. The more alternating layers, the more protection. If you have 3 to 5 alternating layers, you shouldn't have to worry about too much.

It is not enough to insulate your phone from the EMP waves. It is best to place your device in a plastic bag and wrap it with aluminium foil for extra protection.

After the EMP blast, leave the items there for 24 hours or more, till there are no more signs of another EMP triggered bomb or EMP waves. Then you are clear to use it.

It would come from above, but it will reflect and refract off of things around a building. So just using protection on the roof would be pointless.

A car is already a faraday cage, that's why you don't die when your car gets struck by lightning.

No, because it has to be made of something metal.
