Editing Mu-metal (section)

==Examples==
Mu-metal is used to shield equipment from magnetic fields. For example:
* [[Electric power]] [[transformer]]s, which are built with mu-metal shells to prevent them from affecting nearby circuitry.
* [[Hard disk]]s, which have mu-metal backings to the magnets found in the drive to keep the magnetic field away from the disk.<ref>{{Cite book |last1=Daniels |first1=Ryan J. |last2=McIntyre |first2=Timothy |last3=Kisner |first3=Roger |last4=Killough |first4=Stephen |last5=Lenarduzzi |first5=Roberto |title=SoutheastCon 2015 |chapter=Design and implementation of a Hall Effect sensor array applied to recycling hard drive magnets |date=April 2015 |chapter-url=https://ieeexplore.ieee.org/document/7132879 |pages=1–6 |doi=10.1109/SECON.2015.7132879|isbn=978-1-4673-7300-5 |s2cid=7196422 }}</ref>
* [[Cathode-ray tube]]s used in analogue [[oscilloscopes]], which have mu-metal shields to prevent stray magnetic fields from deflecting the electron beam.
* [[Magnetic cartridge|Magnetic phonograph cartridges]], which have a mu-metal case to reduce interference when [[Gramophone record|LP]]s are played back.
* [[Magnetic resonance imaging]] (MRI) equipment.
* The [[magnetometer]]s used in [[magnetoencephalography]] and [[magnetocardiography]].
* [[Photomultiplier tubes]].
* [[Vacuum chamber]]s for experiments with low-energy [[electron]]s, for example, photoelectron spectroscopy.
* [[Superconducting]] circuits and especially [[Josephson junction]] circuits.
* [[Magnetometer#Fluxgate magnetometer|Fluxgate magnetometers and compasses]] as part of the sensor.
* [[Proximity sensors]] (inductive type)
