Effect of head pitch and roll orientations on magnetically induced vertigo (2015)
Journal Article

High strength static magnetic fields are known to induce vertigo, believed to be via stimulation of the vestibular system. The leading hypothesis (Lorentz forces) predicts that the induced vertigo should depend on the orientation of the magnetic fiel...
