My question would be: Are there EMP secure boxes (containers) where you could store objects (e.g. Laptop, hard drives, cell phone, etc.) that would withstand an EMP attack, where the contents of the box would be EMP guns? (that e.g. The box could be kept normally in the apartment and the objects would be cannon despite an EMP attack)
A magnetic "Faraday cage" should protect.
If it has to go spontaneously, I would just put the stuff in the microwave, but it won't turn on.
