Definitions

  • Webster's Revised Unabridged Dictionary
    • Magnetic compensator a contrivance connected with a ship's compass for compensating or neutralizing the effect of the iron of the ship upon the needle.

Usage

In literature:

The idea of employing a magnet as compensator in a magnetic balance is not new, this disposition having been used by Prof.
"Scientific American Supplement, No. 430, March 29, 1884" by Various
The investigations on magnetism led to the important practical discovery of a means of rectifying or compensating compass errors in ships.
"Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 3" by Various
She had expected personality, magnetism, as a compensation for nature's external economies.
"Ancestors" by Gertrude Atherton

In news:

Compasses can be compensated (historically using obvious compensating balls) for the hull magnetism, and must be adjusted periodically if accuracy is important.
Integrated circuits compensate magnetic drifts and enable stable performance over temperature and lifetime.

In science:

To compensate for possible left-right detector asymmetries, the polarity of the dipole magnet used to measure the pion momenta was frequently changed.
Kaons: Review and Outlook
The final section of the beam comprises several additional bending and quadrupole magnets that fine-steer the beam on the target and, during transverse polarisation data taking, compensate for the horizontal deflection induced by the 0.5 T transverse dipole field of the polarised target.
The COMPASS Experiment at CERN
Although the compensating magnets had to be removed when the focusing magnets were installed for the luminosity upgrade, HERA still achieved longitudinal e± beam polarisations with luminosity weighted means of typically 30% and maximum values of up to 40 − 50 %.
Collider Physics at HERA
In the extraction line, corrector magnets are needed to successfully compensate possible deflections resulting from misaligned beam and detector solenoid axes.
Executive Summary of the Workshop on Polarisation and Beam Energy Measurements at the ILC
The cycle is continued until all the three orthogonal magnetic field vectors are compensated to zero. The uncertainty of the compensation is decided by the resolution and bandwidth of the measurement system which is shown by the value of deltaBx, deltaBy and deltaBz after converging.
