What is EMP and what are EMP Bags?
EMP or Electro Magnetic Pulse is also referred to 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 created by EMP is oftentimes disruptive or damaging to the electronic devices and equipment. At higher energy levels, powerful EMPs like a lightning strike is enough to destroy physical objects like aircraft structures, buildings and so on. The effect management of EMP is an extremely important branch of EMC or Electromagnetic compatibility engineering. The truth is, EMPs today are weaponized in order to deliver the damaging effect it has to enemies.
This is when the Faraday cage was created. In reality, this is named after Michael Faraday and it is a form of device that is designed to protect electronic devices from any type 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 – wrap the device inside a plastic wrap or put it in the plastic bag. This will create barrier between conductive aluminum layer and the device. Aside from protecting your device from EMP, this can protect it as well from water.
Step number 2. Cover every inch of your device with aluminum foil – in this case, the aluminum foil serve as a conducting layer which is the reason why it should be done. Make it a point that the aluminum foil has no tears or gaps otherwise, it won’t be that effective. Preferably, make use of your hands in molding the foil around the 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. In between layer, it is recommended to add plastic layer to be able to maximize the protection it makes. By doing so, it is going to create an alternating layer of both conductive and non-conductive materials and protect your device from electromagnetic radiation.
