Abstract
Provided is a magnetic field measuring device including a first sensor unit which includes a first coil sensor configured to output a first sensor signal, a second sensor unit which includes a second coil sensor configured to output a second sensor signal and disposed in a direction perpendicular to the first coil sensor, a third sensor unit which includes a third coil sensor configured to output a third sensor signal and disposed in a direction perpendicular to the first and second coil sensors, and a digital signal processor outputs magnetic flux density based on a voltage difference between the first and fourth nodes, wherein the first to third sensor units respectively output first to third output signals in which specific voltages of the first to third sensor signals are maintained for a predetermined period of time.
