This chapter is focused in the different optical structures and materials that have been used for the development of optical fiber magnetic field sensors and optical fiber current transducers. First of all, this chapter starts with a short introduction of the main fields of application of these sensors and where they are used, and how materials can be classified with regard to their magnetic behavior. Then, a brief review of different ways of measuring magnetic fields will be made. It will be also introduced the main magneto-optical effects. A brief summary of the different options that have been developed by now will be made, showing the evolution of this research field. Then, a deeper look at the most used structures, the most common materials and the devices having greater sensitivity and resolution will be made.
