Mu-metal, or μ-metal, is a soft nickel–iron ferromagnetic alloy with very high permeability, which is used for shielding sensitive electronic equipment against static or low-frequency magnetic fields.

…of sheet materials under DC and low frequency magnetic fields can also be assessed. Low levels of ambient magnetic field are attained using a 5 layer Mumetal enclosure. Various coil systems and highly sensitive field sensors may be used for the calibration of novel magnetic sensors. Acoustic noise emanating…
