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.

9 Minute ReadIntroduction In this post the emission spectra of the Noble Gases are presented. The noble gases constitute the last group (Group 18) in the Periodic Table of the elements. Emission lines obtained from the spectra of these noble gases can be very useful for the calibration of a spectrometer. Historically, these elements were called the
