In this study, we constructed a magnetic field system with a circumferential magnet array of small permanent magnets and evaluated it using a diamond ensemble magnetic quantum sensor, aiming at bias field uniformity and magnetic field noise reduction for phase relaxation time and phase coherence time extension, in order to achieve higher sensitivity of quantum sensors using ensemble NV centers.
