Abstract:
A sensor measures the interaction of an applied magnetic field to an iron sample surface to determine whether the sample surface has been graphitized. The sensor measures the magnetic force resulting from the interaction or the magnetic flux density to determine the content of magnetic material in localized regions of the sample surface. The sensor includes a cantilever beam with a strain gauge for measuring magnetic force. Alternatively, the sensor includes a magnetic flux density sensor to measure magnetic flux density.
