Noun
Meaning

An alloy with high magnetic permeability, consisting of nickel (77%) and iron (15%) with traces of copper and molybdenum.
Examples
Mu-metal cable is easier to construct than permalloy cable, the mu-metal being wound around the core copper conductor in much the same way as the iron wire in Krarup cable.
Uses and properties Mu-metal is used to shield equipment from magnetic fields.
Its higher saturation value allows it to handle stronger magnetic fields, reducing them to a lower level that can be shielded effectively by the inner mu-metal layers.
