Emitted by all kinds of electronic devices, electromagnetic waves exist everywhere. But don’t worry, magnetic shielding helps to protect against these harmful radiations. Unlike our popular belief, magnetic shields actually can’t reduce or block magnetic fields, it works by redirecting the propagation of magnetic field lines so that magnetic flux flows through the walls of the shield itself, resulting in the by-passing of the enclosed area or object needing protection. Obtained 80% nickel, 4.5% molybdenum and the balance iron, Mu Metal is one of the most commonly used alloys in electromagnetic shielding arena. With its unique compositions, Mu Metal has high permeability properties, which in turn lead to its high magnetic susceptibility to an applied magnetic field. This alloy can easily absorb the flow of magnetic fields because of its physical properties. EMI shielding engineers leverage this very property to redirect radiations away from areas they want to make free of EMI. General...
