Abstract
I present a study of the electromagnetic coupling through the coilmagnet pairs used as actuators in Advanced Virgo (AdV) Input Mirror Payloads. We first employed and validated a finite-element analysis approach, followed by a series of stimulated magnetic noise injections in the interferometer, both leading to an estimation of the magnetic noise contribution to the total AdV strain noise. At this stage, AdV seems to be unaffected by magnetic noise. However, we foresee a non-negligible coupling once AdV reaches the design sensitivity. Finally I present the most recent efforts concerning Schumann global magnetic resonances, whose detection and successful subtraction could make the observation of a Stochastic Gravitational Wave Background possible.
