dc.description.abstractMagnetic field sensing has the potential to become necessary as a critical tool for long-term subsurface geophysical monitoring. The success of distributed fiber optic sensing for geophysical characterization provides a template for the development of next generation downhole magnetic sensors. In this study, Sentek Instrument&rsquo;s <i>picoDAS</i> is coupled with a multi-material single mode optical fiber with Metglas<sup>&reg;</sup> 2605SC cladding wire inclusions for magnetic field detection. The response of acoustic sensing fibers with one and two Metglas<sup>&reg;</sup> 2605SC cladding wires was evaluated upon exposure to lateral AC magnetic fields. An improved response was demonstrated for a sensing fiber with in-cladding wire following thermal magnetic annealing (~400 &deg;C) under a constant static transverse magnetic field (~200 &mu;T). A minimal detectable magnetic field of ~500 nT was confirmed for a sensing fiber with two 10 &mu;m cladding wires. The successful demonstration of a magnetic field sensing fiber with Metglas<sup>&reg;</sup> cladding wires fabricated via traditional draw processes sets the stage for distributed measurements and joint inversion as a compliment to distributed fiber optic acoustic sensors.en
