corrugated magnetic shielding?
« on: September 24, 2021, 08:03:57 pm »
Has anyone done any experiments with corrugated steel and wiring to see what the effect is on low frequency noise, as a way to shield a cable other then twisted pair for that frequency range?

I only have aluminum spiral, and it seems you need a helmholtz setup to test this, but has anyone seen the results of this type of shielding?

not a bad project to make the tester either.. I just want to see if there is a reason not to do so more then if there is a reason to do so

it depends on what kind of field you're want to shield. You can calculate attenuation level from known material properties and distance from the source. The most complicated is a shielding from magnetic field within near field zone from a source.
