The measurement of the magnetic field is often the final verification of the design and fabrication process of a magnets for particle accelerators. In most cases, when seeking high accuracy, the measurement technique and its realization can result in a considerable effort. The lecture describes the most used field-measurement techniques based of flux-metric methods: i)the rotating coil method gives a complete two-dimensional description of the magnetic field in terms of normal and skew multipoles; ii) static coils are employed in case of fast-ramped or curved magnets; iii) the single stretched wire is the reference instrument to measure field integrals and to find the magnetic axis.
