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 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.
In most cases, EMP is creating disruptive or damaging interference to our electronic devices and equipment. At higher energy levels, powerful EMPs similar to lightning strike is more than enough to lay destruction to physical objects like aircraft structures, buildings and so on. The management effect for EMP is vitally important branch of EMC or Electromagnetic compatibility engineering. 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. 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 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. To an average individual, this seems complicated by in reality, anyone can have a DIY Faraday cage with aluminum foil.
Be sure that you follow the steps in the next lines if you like to learn how this could be done.
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 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 – 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. In molding the foil around the device, it is great if you’d use your hands. This is basically the first of 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.
