The fabrication and characterization of a distributed magnetic field optical fiber sensor based on magnetostriction method is presented. A conventional single mode fiber (SMF) is coated with nickel-acrylate mixture, with volume ratio of 1:3. The coated SMF is characterized under scanning electron microscope (SEM) to observe the thickness and the morphology of the coating layer. The sensor response was measured by using the Rayleigh backscattering frequency shift method. The results show that the frequency shift is directly proportional to the applied magnetic field. At the magnetic field strength of 95 mT, the sensor response is −2 GHz of frequency shift. The sensitivity of the sensor is 0.09346 GHz/mT (below 10 mT) and 0.01008 GHz/mT (above 10 mT).
