Figure 1: CRT with coils in Helmholtz configuration. The hot cathode emits electrons which are then accelerated through potential difference Vacc. When the electrons enter the magnetic field B, which is perpendicular to their velocity, they move on a circular path with radius r. The magnetic field is due to coils in Helmholtz configuration (2 coils separated distance that equals their radius). The magnetic field due to one of the coils with radius R, at a point on the axis distance z away from the center of the coil, was found using the Biot-Savart law: HOIR?N B1 2(R2 + z2)ž

Question 1. Plot a Graph with the data in Table 2, use Magnetic Force as the vertical axis and Current as the horizontal axis. Perform a linear least squares fit on the Graph, record the slope, intercept, and correlation coefficient in the Table 3. [Refer to Appendix 3_ Graphical Analysis of Experiment Results.docx]. Assume the horizontal copper trace on the Magnetic Force Board perfectly perpendicular to magnetic field, determine the magnitude of the magnetic field B, show your calculation in Table 3.

This problem is in 3D. P is the center. Out of the page is a distance z from P. Let this z be 0.04 m. Calculate the "net" magnetic field at z provided that 1 = 358 A, a = 0.03 m, and b = 0.05 m. Use μ = 1.257x10-6 Wb/Am b NOTE: You will use here the right hand rule and superposition of magnetic field. Out of the page is +, while into the page is -. Final answer in FIVE decimal places. Ignore the effects of the straight wire at the bottom. Include the SI unit. Add your answer
