Answer :
For our delicate measurement equipment to continue to operate accurately, gaussmeter calibration is necessary. In order to achieve this, we compare the instrument to one with a standard or greater accuracy. Then, if there is a deviation from the actual reading, we find it and fix it.
How is a magnetic field calibrated?
By delivering a reverse field to the magnet that is strong enough to bring the output (of flux) down to a reasonable level, magnetic calibration is accomplished.
Using a Tesla or Gauss metre, one may determine the intensity of a magnet's magnetic field. Many people who utilise magnets today possess their own Gauss metres and decide what magnetic field strengths are acceptable. The magnet analyzer will measure the magnetic field strength for multi-polar magnets.
The Hall Effect in semiconductors is the basis for how a digital Gauss metre functions. A voltage is created at a right angle to the current route when a semiconductor with current flowing in one direction is introduced perpendicular to a magnetic field.
