TOP 10 FARADAY F.A.Q.

Here are the Top 10 most Frequently Asked Questions about Faraday Cages. Keep in mind that a intentional strategic EMP attack would have far greater damage than a natural occurring solar flare.

#1. Will a galvanized steel trash can make a good Faraday cage?

Yes, but will have to line the walls with cardboard so that no electronics touch the metal. You’ll also need to tape the lid onto the can using HVAC metallic tape CLICK HERE.

#2. Will a microwave work as a Faraday cage?

No. The microwave is not a Faraday cage.

#3. Can you EMP-proof a car?

You could build a Faraday cage, or store the vehicle in a shipping container. However, you better hope that the vehicle is parked within during an EMP event.

Instead, consider procuring a pre-1980’s vehicle which are purely mechanical (no computers). Additionally, you could buy and store any extra parts within a faraday cage.

#4 Will my mobile phone work if stored in a Faraday Cage?

Yes, your phone will work. However, not only could not use your phone while it’s in the cage, it would not be able to do much without connection to the internet / phone towers. All of the storage and non-internet related Apps (like the calculator and photo app) could still be beneficial.

#5. Do I need to store batteries in a Faraday cage?

No. They have no computer circuitry and would be unaffected. Do consider storing a battery charger in the cage however.

#6. Do I need to keep my solar panels in a Faraday cage?

No. The only part of the system you have to worry about is your solar panel inverter. Don’t worry about your solar panels; they will be fine. It’s best to buy an extra inverter and keep it in your Faraday cage so you can replace the useless one after the EMP.

#7. If I wrap electronic devices in heavy duty aluminum foil, will that work?

Yes and No. The electronics can’t touch the metal. So if you wrapped the electronic devices in paper or a plastic bag first and then wrapped them in several layers of heavy duty aluminum foil, that should do the trick. You should consider doing this AND placing it in a galvanized steel trash can DIY Faraday cage.

#8. If you just unplug your devices from the wall, will they be EMP-proof?

No.

#9. How do I test my Faraday cage?

You can test any device that you think might work as a Faraday cage with a radio. Simply turn on the radio and place it inside the device. If the radio is still receiving a signal, then it’s not a Faraday cage. If you don’t have a radio, you can use a mobile phone, but the results won’t be 100% accurate in the sense that if your mobile phone still rings, then it’s definitely not a Faraday cage, but if it does not, you can’t really be sure. You need to test it with a radio to be 100% sure you have a Faraday cage.
