Popular Shielding Applications of MuMetal

– Shielding from Earth Magnets
– cathode ray tubes (CRTs) used in oscilloscopes
– sensitive electronic equipment against magnetic field
– AC magnetic circuits
– shield against electric field
– telegraph cables
– Electric power transformers, which are built with mu-metal shells to prevent them from affecting nearby circuitry.
– Hard disks, which have mu-metal backings to the magnets found in the drive to keep the magnetic field away from the disk
– Cathode-ray tubes used in analogue oscilloscopes, which have mu-metal shields to prevent stray magnetic fields from deflecting the electron beam
– Magnetic phonograph cartridges, which have a mu-metal case to reduce interference when LPs are played back
– Magnetic resonance imaging equipment
– The magnetometers used in magnetoencephalography and magnetocardiography
– Photomultiplier tubes
– Vacuum chambers for experiments with low-energy electrons, for example, photoelectron spectroscopy
– Superconducting circuits and especially Josephson junction circuits
– Fluxgate magnetometers and compasses as part of the sensor
