Magnetic Measurements Laboratory
Lab Misure Magnetiche 2

The INRiM Magnetic Measurements Laboratory performs certified tests related to industrial projects and internal research activities, regulated by INRiM Technical Procedures, in accordance with the CMCs declared within the MRA and Quality System. 

Specifically, the following tests are performed:

  • Normal magnetisation curve and relative permeability curve in DC – ballistic method (Reference standards: IEC 60404-2 (EPSTEIN), IEC 60404-3 (SST), IEC 60404-4 (Toro));

  • DC hysteresis cycle on ferromagnetic samples in Epstein format; SST; toro – ballistic method (Reference standards: IEC 60404-2 (EPSTEIN), IEC 60404-3 (SST), IEC 60404-4 (Toro));

  • Normal magnetisation curve and relative permeability curve in DC – permeameter method (Reference standard: IEC 60404-4; ref. 4.4);

  • DC hysteresis cycle – permeameter method (Reference standard: IEC 60404-4; ref. 4.4);

  • Characterisation of magnetic materials in AC – magnetic characterisation of ferromagnetic materials under dynamic magnetisation (Reference standards: IEC 60404-2, IEC 60404-3, IEC 60404-6, IEC 60404-10)

  • Magnetic susceptibility and permeability in weakly magnetic materials – fluxmetric method (Reference standard: IEC 60404-15).

These activities are fundamental for the development of theoretical and applied research projects related to energy transition. The objective is to advance technical skills and interpretative models for the study and measurement of magnetic materials, with a focus on international directives for energy transition. 

The requirements of the energy transition and the gradual abandonment of fossil fuels call for new paradigms in the generation, distribution and conversion of electrical energy, together with commitments to energy efficiency and careful physical modelling of the magnetic materials used as cores in electrical machines operating under unconventional power supply conditions and continuously increasing operating frequencies. The synergy between accurate measurement techniques and interpretative models with wide application in the field of magnetic materials is available in only a few laboratories worldwide. 

INRiM boasts a recognised leadership in this field and, by stabilising these activities, is able to provide solid expertise in both the preparation and development of materials and the modelling of magnetic properties.
