Magnetometer Isolate from Interference

[ives]

Hi! How are you? Thanks for taking time to read my e-mail. I'm trying to use a magnetometer to identify the direction that it is pointing. I am able to calibrate the magnetometer in the lab and measure the right angle in degrees. The problem is that the magnetometer has to measure the right angle if it is placed on a metal and I will not be able to recalibrate it. Can you help me with two questions?

1. Do you know something (material) to use to isolate the magnetometer from ferromagnetic materials?

2. Do you know if the magnetometer has to be recalibrated after a long time (> 1 year)?

Best regards,

Ives Oliveira.

Hi Ives,

1. There is no way to shield the magnetometer since you would also shield it from the Earth's magnetic field you want to measure.

2. Yes, both the environmental interference and temperature variations can throw off initial one-time calibration. Our reference software calibrates typically every few minutes to track these variations.

Regards,

Tomas
