| Magnetometer - the History |
The
magnetometer is an Instrument for measuring the strength and sometimes
the direction of magnetic fields, including those on or near the Earth
and in space. Magnetometers are also used to calibrate electromagnets
and permanent magnets and to determine the magnetization of materials.
Magnetometers specifically used to measure the Earth's field are of two
types: absolute and relative (classed by their methods of calibration).
Absolute magnetometers are calibrated with reference to their own known
internal constants. Relative magnetometers must be calibrated by
reference to a known, accurately measured magnetic field.

| A New Perspective on Magnetic Field Sensing |
Magnetic
field sensing technology has been driven by the need for improved
sensitivity, smaller size, and compatibility with electronic systems.
This overview addresses the various types and applications of magnetic
sensors, with particular attention to giant magnetoresistive materials.
