In movies/ fictional novels, solar flare and EMP will render all electronics devices unusable. Is this true?
In: Physics
No. An EMP, whether it’s from the sun or a nuke, is really just a blast of radio waves. Like all radio waves, these require an antenna of some sort to be picked up, and they can be blocked by metal.
Small components like chips will be pretty safe, but the wires between them (if not shielded) might cause harm. Often it’s as simple has forcing the device to restart.
