Abstract
The magnetic field detector includes an x-axis magnetic sensor, a y-axis magnetic sensor, and a z-axis magnetic sensor for detecting magnetic field components in three orthogonal axis directions. Each of the magnetic sensors includes a magnetic impedance element having an impedance that varies in accordance with an ambient magnetic field and an output circuit configured to output a magnetic field detection value that varies in accordance with the impedance of the magnetic impedance element. The magnetic field detector includes an oscillator configured to supply a common drive signal to the magnetic impedance element of each of the magnetic sensors, wherein each of the magnetic sensors outputs, in response to the drive signal, the magnetic field detection value from the output circuit.
