It is very important to accurately measure magnetic properties of ferrous materials in the development of improved electric motors and generators. The pure magnetic properties of new generation amorphous materials show better performance, however forming or cutting the base material decreases these excellent properties because of the mechanical and/or thermal stress caused by the cutting technology. To allow development of the adequate cutting technology for amorphous materials, the effect of cutting on the magnetic properties need to be determined. This can be done by developing a specialized instrument that is capable to accurately measure magnetic properties of small sized amorphous ribbons. This paper introduces the main challenges in the development. Generation of strong magnetic field for the excitation of the specimen is required while small B field is measured in the same place and in the same time, which makes the system quite sensitive to design, building accuracy and calibration.
