There are two basic types of magnetometer measurement. ''Vector magnetometers'' measure the vector components of a magnetic field. ''Total field magnetometers'' or ''scalar magnetometers'' measure the magnitude of the vector magnetic field.<ref name=Edelstein2007>{{cite journal|last=Edelstein|first=Alan|title=Advances in magnetometry|journal=[[Journal of Physics: Condensed Matter]]|date=2007|volume=19|issue=16|pages=165217 (28pp)|doi=10.1088/0953-8984/19/16/165217|doi-access=free |bibcode=2007JPCM...19p5217E|s2cid=108531365|s2cid-access=free|id={{zenodo|1235730}} }}</ref> Magnetometers used to study the Earth's magnetic field may express the vector components of the field in terms of [[Magnetic declination|''declination'']] (the angle between the horizontal component of the field vector and true, or geographic, north) and the ''inclination'' (the angle between the field vector and the horizontal surface).<ref name=Tauxe2014>{{cite web|last1=Tauxe|first1=L.|last2=Banerjee|first2=S.K.|last3=Butler|first3=R.F.|last4=van der Voo|first4=R.|title=Essentials of Paleomagnetism: Third Web Edition 2014|url=http://earthref.org/MAGIC/books/Tauxe/Essentials/WebBook3ch2.html#x4-140002|publisher=Magnetics Information Consortium (MagIC)|access-date=30 March 2014}}</ref>

''Absolute magnetometers'' measure the absolute magnitude or vector magnetic field, using an internal calibration or known physical constants of the magnetic sensor.<ref name=IAGA1996>{{cite book|author1=JERZY JANKOWSKI|author2=CHRISTIAN SUCKSDORFF|name-list-style=amp|title=IAGA GUIDE FOR MAGNETIC MEASUREMENTS AND OISERVAIORY PRACTICE|date=1996|publisher=International Association of Geomagnetism and Aeronomy|location=Warsaw|isbn=978-0-9650686-2-8|page=51|url=http://iugg.org/IAGA/iaga_pages/pdf/IAGA-Guide-Observatories.pdf|url-status=dead|archive-url=https://web.archive.org/web/20160304080050/http://iugg.org/IAGA/iaga_pages/pdf/IAGA-Guide-Observatories.pdf|archive-date=4 March 2016}}</ref> ''Relative magnetometers'' measure magnitude or vector magnetic field relative to a fixed but uncalibrated baseline. Also called ''variometers'', relative magnetometers are used to measure variations in magnetic field.

Magnetometers may also be classified by their situation or intended use. ''Stationary magnetometers'' are installed to a fixed position and measurements are taken while the magnetometer is stationary.<ref name=Edelstein2007/> ''Portable'' or ''mobile magnetometers'' are meant to be used while in motion and may be manually carried or transported in a moving vehicle. ''Laboratory magnetometers'' are used to measure the magnetic field of materials placed within them and are typically stationary. ''Survey magnetometers'' are used to measure magnetic fields in [[geomagnetic]] surveys; they may be fixed base stations, as in the [[INTERMAGNET]] network, or mobile magnetometers used to scan a geographic region. An early adoption (in the 1950s) of airborne magnetometry by [[Inco]] prompted the discovery of [[Thompson, Manitoba]].<ref name="thompson60">{{cite book |last1=Thompson |first1=John Fairfield |last2=Beasley |first2=Norman |title=For the Years to Come: A Story of International Nickel of Canada |date=1960 |publisher=Longmans, Green & Co |location=Toronto}}</ref>
