Re: Taking Minibots on Airplanes
That 5 mGauss limit at 5 m might be an issue.
If you postition additional magnets to form a quadrupole arrangement, the field will drop off more rapidly with distance (1/r^4) than for a magnetic dipole.
You can also look into mu-metal shielding. You'll need to degauss the shield first.
You can use Boy Scout compass to test for excessive fields.
