There are lots of electronics devices that will be affected by the EMP strike. You can get a perfect solution for the protection of your electronic devices. The faraday cage is an ideal solution because the cage is specifically designed with an insulated enclosure to protect your devices. You can protect all those electronics in the cage that you want to protect. The cage can disperse the electromagnetic waves around it without letting the waves passed inside the cage. The cage is easy to prepare and you can use a conductive box and a metal trash can design this cage.
Line a cardboard inside the box and use metallic seal between the drawers and the lid. You can place your cell phone in it to test the cage. Make a call on the phone and see if the phone is ringing. If the phone is buzzing then the confine can’t protect electronic devices. Though the use of Faraday cage is not a fool-proof plan for the EMP, but it is still better than nothing.
