How Would a Nuclear EMP Affect the Power Grid

How a nuclear blast in the upper atmosphere could disable the power grid. The bundle deal with Curiosity Stream has ended, but you can still get a great discount on Nebula and support Practical Engineering here: 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. EPRI Study: Practical Engineering is a YouTube channel about infrastructure and the human-made world around us. It is hosted, written, and produced by Grady Hillhouse. We have new videos posted regularly, so please subscribe for updates.
