Providing new traceability routes for low magnetic field measurements in Europe
The project has started on July 1st, 2025, and will end on June 30th, 2028.

Measurements in the low magnetic field range, from around 10 μT up to 10 mT, are increasingly required by industry due to strong demand and recent developments in key areas such as electric mobility (sensors embedded in electric motors, magnetic encoders, etc.), the medical sector (safety and compatibility of magnetic field-based diagnostics such as MRI and magnetoencephalography), industry, and magnetic field sensing applied to the detection and localisation of ferromagnetic and conducting objects in safety applications and prospecting for natural mineral resources. However, only very few European NMIs have the required capabilities to perform traceable measurements in the low magnetic field range. Consequently, the adoption of novel technologies and materials is hindered by the lack of pan-European metrological expertise in this area. The MetroMag project, funded by EURAMET, will establish standards to measure weak magnetic fields, develop a transfer standard to enable easier and faster comparisons, develop novel methods to cancel environmental magnetic fields, and establish a European infrastructure in the low magnetic field ranges to address the stakeholders’ needs.
