## Homework Statement

[/B]

I am working on a experiment on finding the Earth's magnetic field strength in Denmark. Using a Galvanometer and a constant power source of 5.1V and slowly adjusting the resistance, I was able to find the changes in angle in relation to the changes of current.

Then I used the equation to find the Bh, the horizontal component BH of the Earth's magnetic field.

Here is the Excel spreadsheet on my Google Drive.

## The Attempt at a Solution

However, my calculation shows my Bh is 5.62E-04, while the actual Bh is 5.03E-05. There is a difference of factor of 10!!! I went through the calculations with my teacher, but she could not find the problem. I am hoping that someone can help me locating the error in the experiment/calculation.

I would really appreciate any help! Thank you!
