Abstract

This paper describes the construction of a Helmholtz coil to be used as a magnetic field generator during the calibration of magnetic field sensors. A magnetic field meter was calibrated using the coil to test its efficiency. The obtained results were then compared to the meter’s calibration sheet.

Keywords

calibration, uncertainty, magnetic fields, magnetic field measurement, coils.
