The VLS manifests as a `fictitious' magnetic field, which we perceive as a change in the Larmor frequency of two spinor condensates exposed to different intensities of elliptically polarized light. We use our measurement scheme to diagnose the light-induced magnetic field and suppress it to $2.1(8)\\times10^{-4}$ of its maximum value, by making the trapping light linearly polarized with a quarter-wave plate in ea","authors_text":"A.
