The optical fiber magnetic sensing element (OFMSE) based on the optical fiber coated with composite coating polymer-magnetic powder has been already introduced in magnetic field sensing. In this research, the rapid quenched Nd-Fe-B powder with Nd rich content was used as magneto-active component in composite coating. Magnetic powder was dispersed in poly-(ethylene-co-vinyl- acetate) - EVA solution in toluene. The influence of magnetic powder content (20, 30, 40 and 50 mass %) in composite coating of multimode optical fiber on the thickness, hardness and uniformity was observed and discussed. Sensitivity and reversibility of the constructed OFMSE in the external magnetic field are illustrated.
