So I have a story about humans far off in the future on a different planet that have evolved to be more in tune with electromagnetism and magnetism. Their technology mostly works because of magnetism. And they worship crystals that give off "magnetic vibrations". They don't know what magnetism is really.
And neither do I... so,
is there any evidence that the human brain could pick up magnetic disturbances, fields, waves or something similar? So my magic rocks can "communicate" to my humans telepathically.
P.S. This is not actually magical I want it to be fairly believable/scientifically accurate.
