Correction: 10:32 I meant to say "earth’s magnetic field," not "earth’s gravity."
Correction: A previous version of this video included a segment where I used a doorbell transformer to demonstrate core saturation. That model did not correctly demonstrate the phenomena I was describing, so I cut it from the video.
This video is a summary of the EPRI study on the impacts that a high-altitude nuclear electromagnetic pulse (HEMP) would have on the US power grid. It’s the first in a deep-dive series of videos about large-scale threats to the grid.
