Abstract

We need information on the magnetic permeability of the material. Several applications for permeability values are needed in producing industrial equipment, such as transformers, magnetic impermeable casing, and magnetic field antennas. However, the accuracy of a magnetic permeability measurement device depends on the range of magnetic permeability values of the material used. Several magnetic permeability test methods can be carried out using guided and unguided measurement systems. However, these methods require high complexity, precise and stable calibration, special geometry, and a limited range of permeability measurements.
In this paper, we test a prototype of a more efficient and flexible magnetic permeability measurement system. This prototype test was carried out on annealed and non-annealed ferrous metals. The results show the stable measurement and that the annealed iron has a higher magnetic permeability value than the permeability of an unannealed iron. The prototype of the measurement method shows good sensitivity to the measurement of the magnetic permeability of a material.
