A scanning Hall probe microscope (SHPM) equipped with three GaAs films was developed.

The magnetic field intensity decreases during crack growth.
- class="label">•
Polarization of the magnetic field occurs ahead of the fatigue cracks.
- class="label">•
The polarization moves while the crack grows.

The magnetic fields move as the plastic area expands.
