Easy way to measure field strenght

[Link]

I was wondering, when using a magnet to track the deviation of Earth's 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 don't know however how this would work out practically.

The apparatus looks like this

If anyone got any creative ideas on how to do this, please post

Yes, it is possible to get a numerical value of the strength of the magnetic deviation during a geomagnetic storm. In order to do this, you would need to measure the magnetic field intensity before and after the storm using a magnetometer or other instrument. The difference between these two values can then be used to calculate the strength of the magnetic deviation. You can also use the angle of deviation to calculate the force applied and then calculate the strength in nTeslas.

Thank you for sharing your thoughts on measuring field strength during a geomagnetic storm. Your idea of using a magnet to track the deviation angle and then calculating the strength in nTeslas sounds like a promising approach. However, as you mentioned, it may be challenging to implement practically.

One possible solution could be to use a magnetometer, which is a device specifically designed to measure magnetic fields. There are different types of magnetometers available, such as fluxgate, proton precession, and optically pumped, and they can provide accurate measurements of magnetic field strength in nTeslas.

Another idea could be to use a Hall effect sensor, which is a semiconductor device that produces a voltage proportional to the strength of the magnetic field it is exposed to. By calibrating the sensor and using it to measure the voltage during a geomagnetic storm, you can calculate the magnetic field strength.

Overall, there are several methods available to measure field strength during a geomagnetic storm, and it may require some experimentation and calibration to find the most accurate and practical approach. I hope this helps and good luck with your measurements!
