I was wondering, when using a magnet to track the deviation of earths magnetic field during a geomagnetic storm, is there in any way possible to get a numerical value of the strenght of the actual magnetic deviation?

I was thinking of recording the angle of deviation, then using another magnet during quiet conditions to create the same deviation angle as recorded, then based on this, calculate the force applied, then calulating the strenght in nTeslas. I dont know however how this would work out practically.

The apparatus looks like this

If anyone got any creative ideas on how to do this, plz post :smile:
