An optical fiber magnetic field sensor is demonstrated using a waist-enlarged fusion bitaper-based optical fiber Mach-Zehnder interferometer (MZI) coated by magnetic fluid (MF). Since refractive index (RI) of the MF is sensitive to magnetic field, differential effective RI of the sensing fiber and h...
