Field Decay and Snapback Measurements Using a Fast Hall Probe Sensor

Characterization of residual stresses in ferrous components by magnetic anisotropy measurements using a hall effect sensor array probe

A new surface sensor probe comprising an angular array of Hall effect sensors has been developed for characterization of residual stresses in ferrous materials by means of stress‐induced magnetic anisotropy measurements. The sensor probe applies a radially spreading ac magnetic field to a test sample, and detects stray fields in different directions simultaneously to determine the principal str...

A Simple and Fast Method for Field Calibration of Triaxial Gyroscope by using Accelerometer

Scanning hall probe microscopy technique for investigation of magnetic properties

Scanning Hall Probe Microscopy (SHPM) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. This method is based on application of the Hall Effect, supplied by a micro hall probe attached to the end of cantilever as a sensor.  SHPM provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...

Using an optical mouse sensor to track geophysical field measurements

To position arbitrary outdoor measurements, the most common methods are the use of global positioning system (GPS) technology or distance tracking from reference locations. The system to be introduced here consists of a combination of an optical distance tracking system and a civil, autonomous GPS receiver. Through the application of a recursive filter, both components support and correct each ...
