Overview

High-sensitivity magnetic field sensors and digital controllers are used to measure magnetic field changes in any direction, and the inverting magnetic field generated by the Helmholtz coil is used to suppress magnetic field disturbances.

Model

● Basic low-frequency active demagnetization system: BAMC-10

● Low-frequency active demagnetization system based on spatial correlation (off-site compensation): AAMC-10

Composition

● Helmholtz coil pair

● Three-axis magnetic field sensor (three-axis magnetic flux gate)

● Feedback and control system

Advantage

● Has good demagnetization properties in low frequency bands

● The high-sensitivity sensor can accurately feedback changes in the ambient magnetic field
