I. Objective. II. Procedure. III. Results. 1. The experimental values for the slope in equation F vs. I 2 are: Slope 1 (one current direction) Slope 2 (reversed current direction) Average experimental slope N/A 2 N/A 2 N/A 2 2. The relative discrepancy between the average experimental slope and the expected theoretical slope of N/A 2 is: relative discrepancy = (Average exp. slope – Theor. slope)*100% / Theor. slope = =
IV. Data Analysis. The experimental conditions for our current balance were as follows: a = optical lever arm = distance between the movable rod and the fulcrum = cm b = perpendicular distance between the scale and the mirror (or the fulcrum) = cm L = the effective length of the parallel conducting rods =

Unformatted text preview: cm D = diameter of the conducting rods = 0.318 cm x 1 = telescope reading for the current balance in equilibrium = cm x 2 = telescope reading for the current balance when rods are touching = cm z = real surface-to-surface separation between rods in equilibrium = a * ∆ x / 2b = = cm The complete set of data (I 1 , I 2 and m) with graphs of F vs. I 2 is presented in the attached Graphical Analysis printout. The experimental average slope from the plots for the two current directions was calculated as follows: Average slope = The theoretical slope of the relationship F vs. I 2 for our current balance in equilibrium was calculated, assuming μ 0 = 4 π * 10 -7 T*m/A, according to the following equation: d = real center-to-center distance between the rods in equilibrium = = z + D = cm V.
