Like how you can fry your electronics if they’re plugged in when the power comes back on from an outage, why can’t we “unplug” everything so to speak?
In: Planetary Science
The issue is that an EMP causes electricity to start flowing on its own, even without a power source. That’s how we generate electricity in the first place (mostly): a spinning magnet will cause electricity in a wire near it.
An EMP is a massively powerful magnet forming, and it will cause electricity to “materialize” inside most metal things. It would be easy to build a light bulb that light itself up in response to an EMP going off using the EMP itself as the power source even at a distance.
Unplugging stuff isn’t going to help much. Electricity will just happen anyway, and electricity at the wrong voltage and flowing the wrong way through parts can ruin them.
