As a prepper one is introduced to the concept of an EMP (electromagnetic pulse) blast and the aftermath through books like One Second After and Lights Out. We also have had television series like Jericho and Revolution that started with a flash….. The EMP blast is used quite often in PAW fiction but fiction is fiction or is it? Is an EMP a reality and should you be prepping car parts, have a faraday cage? EMP's reality or fiction?
