Not that I know any better, but wouldn't it be easier to build a mu-metal shielded enclosure to exclude the Earth's magnetic field (and anything else, eg. from nearby wiring), and then generate your own calibration field with a Helmholtz coil?
- nextaccountic 4y agoCan you actually shield a magnetic field like you do for electric fields with Faraday cages?
- kimburgess 4y agoNot stable ones.
- jbay808 4y agoI'm not sure what you mean by this. You certainly can shield a static magnetic field by using a magnetically soft material.
- kimburgess 4y agoYes, but that's not a faraday cage.
- jbay808 4y agoAh. I think we're parsing nextaccountic's ambiguous grammar differently. My reading: "Can magnetic fields be shielded (by mu-metal), like a Faraday cage shields electric fields?" vs your reading: "Can a Farafay cage shield magnetic fields like it can shield electric fields?"
- kimburgess 4y agoYep, I was being pedantic meanwhile you were likely providing useful info :).
- jbay808 4y agoAbsolutely you can. And that's what mu-metal is designed for.
