It is an essential question fundamental to our existence. I would be flabbergasted to learn magnetism is involved in any way with consciousness. It would be very difficult to separate magnetic affects on our brain out from any experiments, and since we have no idea what kind of field or energy consciousness is, it seems we aren't able to measure any impact magnetism might have on it. A difficult conundrum.
I have read reports that consciousness can be shown to communicate through barriers that prevent magnetic fields, in research by Jacobo Grinberg-Zylberbaum. He allowed people to simply sit near each other for some time in darkness, until they felt each other's presence. Then he separated them into rooms with no means of communication, with a Faraday cage between them. When he flashed light into the eyes of one, the other subject responded to the stimulus.
"...the non-materialist model of consciousness—supported by EEG and phenomenological data—suggests that consciousness may be non-local, meaning information transfer between minds could theoretically occur outside conventional sensory channels. This model provides a potential scientific framework for psychic connections, though direct evidence for instantaneous psychic contact with living individuals remains inconclusive.
"In summary, while no definitive scientific proof exists for instant psychic connections to living loved ones, emerging evidence from anecdotal reports, neurophysiological studies, and parapsychological research points to the possibility of non-physical, intuitive communication in emotionally bonded relationships."
If such communication exceeds the speed of light, that suggests consciousness isn't subject to physical laws in the same way all other things in the universe are. Also, I don't believe scientific proof can exist. There can only be evidence.
We find more questions in every answer, when we ask the right questions.
"...that is not going to stop me from thinking about it and wondering about it."
I think that's the right answer!
