Build your own Compass Magnetometer

Monday, 31 August 2009
The instructions for this magnetometer have been taken from an article written by Göte Flodqvist, called 'Detecting the Polar Lights'. This was published in Sky and Telescope, Oct. 1993, p. 85. Some of the components we have used differ due to availablilty but the basic design is unchanged.
