Superficial magnetic imaging by an xy-scanner of three magnetoresistive channels PROJECT TITLE :Superficial magnetic imaging by an xy-scanner of three magnetoresistive channelsABSTRACT:A scanning system developed for planar magnetic surfaces composed of a moving line of three magnetoresistive ultrasensitive transducers, complemented by a signal conditioning circuit is presented. After the calibration of the sensors, it was used to determine magnetized surface images with different shapes to evaluate the sensitivity of the device, and the images are represented in gray levels on a scale from 0 to 255 intensities, to get a visual representation of the magnetic field strength. The device is shown to be sensitive enough to detect gradients homogeneities and discontinuities in the magnetic field maps and images of magnetic susceptibility. Did you like this research project?
