Objectives: To study magnetic fields generated by a square shape current carrying coil. Experimental Procedure: First the length of the side of the coil was measured. Then, the compass was positioned so that the needle was perpendicular to the plane of the coil. A current was then applied and the results were noted. The coil was then turned 180 degrees and then a current was applied again and the needles response was again noted. The coil was then positioned so that the compass was parallel to the plane of the coil. The current was then increased and the needles response was noted. Then the pre-set experiment file for magnetic fields was opened and measurements of the needle deflection versus the current in the coil were taken. In graphical analysis, a plot of

    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.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
