Examples of humans reporting diiziness, vertigo, or nausea in high magnetic fields:
'''Schenck et al. 1992''' PMID 1518472
"A mild level of sensory experiences, apparently associated with motion within the field of the magnet, was reported by some of the volunteers during some of their exposures. A questionnaire regarding sensory effects associated with magnetic resonance scanners and possibly caused by the static magnetic field of these instruments, was given to nine respondents who had experience within both 1.5-T scanners and this 4-T scanner and to another group of 24 respondents who had experience only within 1.5-T scanners. For the sensations of vertigo, nausea, and metallic taste there was statistically significant (p less than 0.05) evidence for a field-dependent effect that was greater at 4 T. In addition, there was evidence for motion-induced magnetophosphenes caused by motion of the eyes within the static field."
'''Kangarlu et al. 1999''' PMID 10609989
In a study on cognitive and cardiac effects of an 8T MRI machine:
"During exposure, subjects were encouraged to verbalize any unusual sensations. The responses to these communications were later recorded on each subject file. According to our subjects, entrance into the magnet and passage through the high gradient region was the dominant characteristic sensations they experienced inside the magnetic field of 8 Tesla. They reported vertigo and metallic taste in the mouth, and slight tingling effects. Most of these reports (except occasional metallic taste) were rare once the subject was positioned at the isocenter. While subjects were being transferred through the region of maximum field gradient, six individuals felt that they needed to lower their insertion rate into the magnet to avoid the unusual sensations. Note, however, that these initial studies were conducted without a patient table."
'''Chakeres et al. 2003''' PMID 12938130
Tests of neuropsychological function in an 8T MRI machine (same machine as Kangarula 1999):
"A few of the subjects commented on mild dizziness or vertigo while entering or exiting the magnet, but there were no significant complaints related to exposure."
