With magnetic field measurement instruments electromagnetic fields are measured for assessing the safety of human exposure to radiation in magnetic fields and for acceptance testing of electrically operated equipment according standards like IEC/EN 62233 (formerly EN 50366), generic standard like IEC 62311 as well as ICNIRP 1998 and ICNIRP 2010. However, in addition, typical applications are direct evaluation of field exposure in comparison with major standards and regulations such as EMF Directive 2013/35/EU for workplaces, office places but also living places.

Typically measurements are taken of electrical installations such as transformers, low voltage distribution, switch gear, busbars, cables, overhead lines and railways. However, DC fields such as from NMR / magnets, tramways and moving metal objects or weak fields inside laboratories, are measured, too. Depending on the measurment instruments, the sensitivity goes  as low as 10pT (picotesla). Typical use are site survey for ebeam applications, measurement of the attenuation of magnetic shielding measures and analysis of interfering frequencies.
