Purpose To measure the force of the magnetic field and the dependence on the separation between the two wires. The magnetic field lines will also be drawn. Theory The magnitude of the magnetic field is shown by the following equation: is the permeability of free space while I is the current. r is the radius of the magnetic field line around the wire. The force is measured by the following: F = B 2 I L L is the length of the conductor and is measured in meters. Another common equation for force is: d is the diameter. The diameter is measured by: d = d 0 + 2R; d 0 = Da/ 2b Analysis and Results 1. What does the value of the slope tell you about the d-dependence of the force between two current carrying wires? Recall: y = x n and ln(y) = n ln(x) a. The value of the slope tells us that as one value increases, the other value increases as well. There is a directional relationship between the two values and it is shown on the graph. 2. How does your answer to question one compare to what is expected? Why?

What students are saying

• 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.
