I know of an 11T MRI (in Paris, IIRC) which knocks people unconscious when they move too fast. Apparently, the field across your skull inhibits (some) spike propagation. Doesn't require that much power.
- xondono 5y agoIt's not unique to MRIs, but it's one of the niche applications where this happens. Working in certain environments (IIRC >2T) requires special training, that include things like "slow walking", since moving too fast would induce currents in the brain that could knock you out. For a product that I worked in we had to find a cheap way to create a 2T static field for validation, the complications of each of the possibilities were amazing.
