Assuming a modern urban fantasy setting (thus, the world is "ours" in the present time, with the known continents, cities, technology, and general environment), what would happen if a supernatural EMP-like event were to knock out all electronics around the world at the same time?
For plot purposes, I need an event able to disable or destroy all manmade satellites (and thus a lot of communication), take down the power grid for (preferably) days, and render communication via cell phones and computers virtually impossible for the forseeable future. Other effects optional! Would an EMP-like event be the best way to do this? If so, what would happen to these specific devices:
a) How would cars - from old, non-computerized models up to the Tesla - react? Would they be disabled, and if so, for how long?
b) How would hospitals react? Would an event capable of knocking out power on this scale temporarily or permanently disable their backup generators, or would they be able to switch over with little to no disruption?
c) Would Internet cables and/or landline telephones be affected, and if so, how?
d) If the event acted like an EMP that successfully (and permanently) disabled all manmade satellites, including communications satellites, what would the effect be on cell phones, Internet availability, and general global communications? Would something that behaved like a real-life EMP be able to knock them out for days or weeks at a time, or would the supernatural event need to have a bit more, er, supernatural to get that effect?
d) Are there any other major side effects, either on manmade structures or on the environment?
e) Bonus: Would this be theoretically achievable with an appropriately-sized EMP or solar flare (thus giving the in-world government a plausible explanation to reduce panic)?
