Then how can we exist around large magnetic fields without them affecting us mentally - no forgetting, no dropping unconscious, no trippy psychedelic experiences - seemingly nothing at all? How come our mains electricity does not not act on our minds analogously to a blowtorch on our skin, or a hydraulic press on our bones?

MRI machines at 3 Tesla field strength are 100,000x stronger than the Earth's magnetic field, and pulsed very fast. They affect the spin of the nucleus of the Hydrogen atoms in the body, but apparently have no effect on the person's brain or consciousness (or biomagnetite)? We wear headphones with electromagnetic coils pulsing music on the sides of our heads for hours at a time, with no effect. We use machine's powerful electric motors, work near them, we're surrounded by alternating currents in wires, some people experiment with Tesla Coils, MagLev capable of lifting trains, wireless power delivery...

(PS. Red / Arctic Foxes might be able to see the Earth's magnetic field and use it to help find mice to hunt; they listen for mice they can't see and jump-pounce into the snow and their jumps are successful at getting the mouse 80% of the time when they are facing North-East and only 18% of the time when they aren't - https://www.nationalgeographic.com/science/article/foxes-use... )

The whole argument hinges on the idea of tuned resonance: https://www.nature.com/articles/s41598-025-07988-2
