There’s a scene in Stanislaw Lem’s novel “Invincible” where an electromagnetic surge “of at least billion Gauss” render an exposed astronaut into a new-born baby, mentally, effectively “formatting” all the memories from his brain. I know this is a SF novel, but Lem was always a hard-liner. So, is this possible, in theory? Could a magnet a size of a planet affect neural connections?
I tried googling the answer, but the results are inconclusive.
