There’s a lot of bad information circling the internet about EMP’s.. most of it is wrong.
EMP’s come in three flavors.. E1, E2 and E3
The E1 pulse is produced by nuclear weapons detonated in space. The pulse is short, measured in nanoseconds, but has a theoretical peak amplitude of around 50,000 volts per meter. Due to the inverse square law of wave propagation, the further out from the center of detonation you are, the smaller the amplitude. Plugged in or not, no unprotected electronics would survive within the highest amplitude radius of the center. Electronics in trash cans would not survive either but if they were packed in multiple EMP shielding layers, they’d have a chance. In the outlying areas around 1000 miles away, electronics stored in DIY EMP cans might have a chance of surviving.. It is still unlikely that your CoreI5 processor would survive but your 1990’s cb radio probably would, a dvd burner probably would, and most other electronics capable of surviving a small over-voltage too.
Want to protect that CoreI5 processor? It should be packed in multiple layers of electromagnetic shielding.. the more layers the better.
An E2 pulse is lightening. Enough said?
An E3 pulse is what we get from a CME (Coronal Mass Ejection). A CME will induce about 1 volt per meter into any conductive surface and will last for time frames measured in minutes or hours. Electronics on the ground that are not plugged into the grid will be safe.. your car will be safe, but the grid will get energized to millions of volts as that 1 volt per meter adds up fast on powerlines that stretch long distances. The grid will be toast, and it will stay that way for up to a decade in some places. An E3 pulse will ignite fires and burn homes down because it lasts so long that its capable of heating the conductors and melting insulation. The Carrington event saw charred and burned areas around the telephone poles due to this effect. Your microwave, television, battery chargers, radio’s, even your furnace controls could also ignite and burn your home down. Fire extinguishers are key here and most folks don’t have them.
Putting your valuables in a microwave is a waste of time for either EMP pulse.
