Measurement

  • Certain measures are sensitive to ambient magnetic fields. In these cases, it is necessary to isolate them to get a reliable measurement.
     
  • Two cases: 
    - from the design of the device, it must be installed a shield
    - when in use, it is necessary to add a shielding in order to create a non-magnetic environment
     
  • Some applications: dosimeter, magnetometer, Hall effect sensor, zero field chamber...
     
  • Shields may be used to calibrate the gauss meters.
