		<description><![CDATA[Whilst mu metal ® is available in many different gauges and indeed a single layer is suitable for most commercial applications, optimal shielding results are obtained when a shield is constructed of multiple layers of mu metal ®. In theory each layer should be of a light gauge and the shield constructed of many layers (T. Rikitake [...]]]></description>

		<description><![CDATA[What is field attenuation? This is also known as the shielding factor (S) and is a ratio of the magnetic field strength outside of the magnetic shield (Ha) and the resultant field on the inside of the shield ie Ha/Hi (no units) or S = 20 x log(Ha/Hi) (Db). There are various formula based on [...]]]></description>

		<description><![CDATA[Specifications : ASTM A-753 Alloy 4, MIL N-14411C Composition. Mu metal is a 80 % Nickel, 4.5 % Molybdenum, balance Iron soft ferromagnetic alloy which means that it does not retain a field after the removal of an external magnetizing force. Mu-metal ® offers exceptionally high initial and maximum permeability with minimum hysteresis loss. It also has [...]]]></description>
