What is EMP and what are EMP Bags?
EMP or Electro Magnetic Pulse is called sometimes as transient electromagnetic disturbance. This is more of a short burst of electromagnetic energy which should not be taken lightly. The pulse may have been originated from natural occurrence or it can be manmade as well and might occur as electric, radiated, conducted electric current or magnetic field depending on the source.
The interference caused by EMP is usually disruptive or damaging to electronic devices and equipment. And given with higher energy level, a strongly powerful EMP such as lightning strike is capable of destroying objects including aircraft structures, buildings and so on. One of the significant branches of EMC or Electromagnetic compatibility engineering is the management of its effect. As a matter of fact, EMPs these days have been weaponize to deliver its damaging effect to enemies.
This is the time when Faraday cage was invented. Actually, this was named after Michael Faraday and this is the type of device that is made intentionally to provide protection on the electronic devices from any kind of electromagnetic radiation. The cage works by layering non conductive and conductive layers, creating a shielding effect for items that are stored inside the cage and protecting it from radiation. Though it sounds a bit complex, anyone can make their very own Faraday cage using just an aluminum foil.
If you wish to learn how this can be done, then make sure that you follow the steps that are listed below:
Step number 1. Wrap your electronic device in plastic layer – find a plastic wrap or a plastic bag and use it to wrap your device or as storage. This is going to create barrier between the conductive aluminum layer and the device. It can serve as waterproof layer as well to get that extra level of protection.
Step number 2. Cover every inch of your device with aluminum foil – the reason why this should be done is that, the aluminum foil act as a conducting layer. In order for this one to be effective, make sure that the aluminum foil you’re using has no gaps or tears. Ideally, use your hands to mold the foil around your device. This act as the first 3 layers of aluminum foil.
Step number 3. Alternate the aluminum foil and plastic – as much as possible, put three layers of aluminum foil. You can also maximize the protection by simply adding plastic layers in between every layer of the foil. By doing so, it will be able to create alternating layer of both conductive and non-conductive materials and thus, protect your device from electromagnetic radiation.
