Unformatted text preview: I 1 and D were not taken into consideration. How would these errors contribute to your final results? Looking down at the coils, their magnetic field is (out of) o r ( into) the coils. Check one. Use the value of I 1 to calculate the Earth’s magnetic field. Compare it to the literature value that may be obtained from the Internet or physics handbooks. What is the direction of the Earth’s magnetic field; into the floor or out of the floor? Why is it imperative to keep the tilt angle and the direction of the coils fixed during the experiment? 4...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
