fluxgate magnetometer

6 Minute ReadIntroduction In several previous posts the physical principles describing the fluxgate magnetometer were introduced. We went on to construct a simple magnetometer based on a single fluxgate sensor, available from FG sensors in Slovenia. This was installed in a small thermos flask to provide some reasonable means of keeping the temperature fairly constant and data from […]

5 Minute ReadUploading the Data to a Website If you have been following so far, at this point we should have the Raspberry Pi set up, configured, and the necessary program modules installed.  This final post describes how to upload the data to a website or server.  The simplest way to do this is to create a shell

11 Minute ReadIntroduction Well, it has taken me a few months to get around to finishing this particular project, but here are the final sections that I have split into two parts. In the Part 1 and Part 2 articles, we covered the basics of the fluxgate magnetometer (FGM). We explained how it can be used to

6 Minute ReadIntroduction In Part 1 of this 4-part post, the fluxgate magnetometer (FGM) was introduced. We outlined how this device can be used to detect changes in the Earth’s geomagnetic field caused by the solar wind. These changes can predict, to some extent, the amount of solar activity and the chances of you seeing an aurora

6 Minute ReadIntroduction Magnetometers are instruments used to measure magnetic fields. They have been around in different forms since the great physicist and mathematician Karl Friedrich Gauss devised the first one almost 180 years ago. Flux gate magnetometers are very useful devices that measure the change in magnetic field strength as a change in voltage or frequency.
