Day 21 Earth's Magnetic Field

Magnetic Field of Earth:

We set up the tool above to determine the magnetic field of the Earth.

Using Biot-Savart Law we calculated the magnetic field for the coil using current, the number of coil turns, radius and the constant.

Then we used the relationship between Earth field, and coil field to determine the field.

We determined by using the compass changing degree and known current to solved for the magnetic field of Earth by dividing the magnetic field of the coil by tangent theta. As the graph below we knew that the slope of the data set would be the magnetic field of the earth.
