Re: Why is Mu Metal used?
(Like many physics explanations, the one below is concise, simple andtoggle quoted messageShow quoted text
We want to shield an M field.
A changing M field *can* be shielded with non-amagnetic conductors
(think like the conductor appears as a short to the induced currents,
thus draining power from the field, weakening it)
A static M field can only be shielded by re-directing it with something
that has high magnetic permeability ("magnetic conductor"). Mu metal is
named after magnetic permeability, because it has such a high mu.
So the mu-metal shield lets the magnetic field flow around the shielded
cavity (for the most part).
