  2. Magnetometer - Wikipedia

    en.wikipedia.org/wiki/Magnetometer

    The caesium and potassium magnetometers are typically used where a higher performance magnetometer than the proton magnetometer is needed. In archaeology and geophysics, where the sensor sweeps through an area and many accurate magnetic field measurements are often needed, caesium and potassium magnetometers have advantages over the proton ...

  3. Vibrating-sample magnetometer - Wikipedia

    en.wikipedia.org/wiki/Vibrating-sample_magnetometer

    A vibrating-sample magnetometer (VSM) (also referred to as a Foner magnetometer) is a scientific instrument that measures magnetic properties based on Faraday’s Law of Induction. Simon Foner at MIT Lincoln Laboratory invented VSM in 1955 and reported it in 1959. [1] Also it was mentioned by G.W. Van Oosterhout [2] and by P.J Flanders in 1956. [3]

  4. SQUID - Wikipedia

    en.wikipedia.org/wiki/SQUID

    A SQUID (superconducting quantum interference device) is a very sensitive magnetometer used to measure extremely weak magnetic fields, based on superconducting loops containing Josephson junctions. SQUIDs are sensitive enough to measure fields as low as 5×10 −18 T with a few days of averaged measurements. [ 1 ]

  5. Muon g-2 - Wikipedia

    en.wikipedia.org/wiki/Muon_g-2

    The next stage of muon g − 2 research was conducted at the Brookhaven National Laboratory (BNL) Alternating Gradient Synchrotron; the experiment was known as (BNL) Muon E821 experiment, [17] but it has also been called "muon experiment at BNL" or "(muon) g − 2 at BNL" etc. [7] Brookhaven's Muon g − 2 experiment was constructed from 1989 to 1996 and collected data from 1997 to 2001.

  6. Scanning SQUID microscopy - Wikipedia

    en.wikipedia.org/wiki/Scanning_SQUID_microscopy

    In condensed matter physics, scanning SQUID microscopy is a technique where a superconducting quantum interference device (SQUID) is used to image surface magnetic field strength with micrometre-scale resolution. A tiny SQUID is mounted onto a tip which is then rastered near the surface of the sample to be measured.

  7. Search coil magnetometer - Wikipedia

    en.wikipedia.org/wiki/Search_coil_magnetometer

    An inductive sensor connected to a conditioning electronic circuit constitutes a search coil magnetometer. It is a vector magnetometer which can measure one or more components of the magnetic field. A classical configuration uses three orthogonal inductive sensors. The search-coil magnetometer can measure magnetic field from mHz up to hundreds ...

  8. Zeeman effect - Wikipedia

    en.wikipedia.org/wiki/Zeeman_effect

    Since the distance between the Zeeman sub-levels is a function of magnetic field strength, this effect can be used to measure magnetic field strength, e.g. that of the Sun and other stars or in laboratory plasmas.

  9. Vanguard 3 - Wikipedia

    en.wikipedia.org/wiki/Vanguard_3

    This experiment had a proton precessional magnetometer to measure the Earth's magnetic field at altitudes ranging from 514 km (319 mi) to 3,714 km (2,308 mi) and at latitudes between ± 33.4°. The measurements were made on command as the spacecraft passed seven Minitrack stations in North and South America and one each in Australia and South ...
