Measuring Magnetic Field Strength
#1
Hello,

I'm currently doing a high school experiment on how temperature affects the magnetic field strength of a neodymium magnet and my teacher recommended Phyphox.

I'm planning to simply record the magnetic field strength before and after the magnet is subjected to an extreme temperature change but was hoping for some advice. I understand that the magnetometer has a calibrated and uncalibrated mode but I don't really understand what this means. I cannot tell the difference between it being calibrated and uncalibrated.

Also, it seems like there's a bit of interference regardless of whether or not the magnets are placed nearby so I assume I have to subtract a value for every result I get. And I'm assuming for this type of test, the absolute magnetometer test might be best? I'm not sure how I could use the x, y, and z separately. 

Any advice would be appreciated.

I'm currently testing this using the Samsung Galaxy S9, by the way.

Kind regards,
Eddy
