What is EMP and what are EMP Bags?
EMP or Electro Magnetic Pulse is also referred to as transient electromagnetic disturbance. Basically, this is a short burst of electromagnetic energy but you should not underestimate its capacity. The origination of the pulse might be from a natural occurrence, it can be manmade and may occur as electric, radiated, conducted electric current or magnetic field which all depends on the source.
The interference caused by EMP is usually disruptive or damaging to 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. In reality, EMPs are also used by the military nowadays by weaponizing its effect.
This is when the Faraday cage was created. It was actually named after Michael Faraday and it’s a type of device that’s intended to provide protection on electronic devices from any sort of electromagnetic radiation. The cage is working by layering both non conductive and conductive layers which creates a shielding effect for the items stored inside the cage and protecting it from radiation. To an average individual, this seems complicated by in reality, anyone can have a DIY Faraday cage with 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. What this will do is establish a barrier between 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 to why this must be done is that, aluminum foil serve as conducting layer. 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 serves as the first of 3 layers of the aluminum foil.
Step number 3. Alternate the aluminum foil and plastic – you must cover every inch of your device with at least three layers of the 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 will be able to create alternating layer of both conductive and non-conductive materials and thus, protect your device from electromagnetic radiation.
