In this work a general introduction to Helmholtz coil is presented and then attention is on a practical implementation of a wideband (50 kHz) coil for high magnetic flux density applications (several mT may be obtained). Field uniformity is within 1.5% and 0.35% inside cubic volumes of 25% and 10% of the coil side respectively, so suitable also for high accuracy applications such as sensor calibration

Abstract
In this work a general introduction to Helmholtz coil is presented and then attention is on a practical implementation of a wideband (50 kHz) coil for high magnetic flux density applications (several mT may be obtained). Field uniformity is within 1.5% and 0.35% inside cubic volumes of 25% and 10% of the coil side respectively, so suitable also for high accuracy applications such as sensor calibration
