Researchers tested whether strong magnetic fields affect nerve signal transmission by exposing isolated lobster nerve tissue to a 1.2 Tesla magnetic field. They found no significant changes in nerve conduction velocity whether the field was applied parallel or perpendicular to the nerve. This suggests that static magnetic fields at this strength don't disrupt basic nerve function.

Researchers tested over 200 people in more than 30,000 trials to see if humans can consciously detect moderate-strength 60 Hz magnetic fields (7.5-15 gauss). Using a specially designed isolation chamber to eliminate false clues, they found no evidence that people can sense these electromagnetic fields, even with biofeedback training.
