This is a picture of the apparatus of used this experiment. This simulates a ring wrapped around a cardboard ring. Used in the is experiment with a power supply varying the amount of current will defect the compass to the right a certain amount of degrees.  

This graph shows the magnetic field of the earth. We calculated the current going through a loop that is wrapped around 30 times. We calculated the magnetic field (B) for the earth and the coil (Bcoil=Bearth*tan(theta)).

The last experiment was Professor Wolfe displaying a spring in relation to looking at a solenoid. A current is then sent through the solenoid. Using a probe which measured the magnetic field. This was  as also calculated making it a ring looped around a number of times using mu(0)*(N/L).
