  "abstract": "The weak guidance approximation suppresses the longitudinal field component $E_z$, and with it an entire class of linear magneto-optic interactions. We derive and experimentally verify a transverse Faraday effect in step-index multimode fibres that couples $E_y$ into $E_z$. Using speckle decorrelation we isolate the linear Faraday signal from the quadratic Cotton-Mouton background, confirming four predictions: the effect vanishes without a strong index step, scales with launch angle, is completely polarisation-selective relative to the field, and tracks Verdet dispersion. Under 0.24 T we observe $Δρ\\approx 0.16$ for perpendicular input and a complete null for parallel input.",
