Portfolio Introduction: This portfolio will investigate how to create an equation that has a line of best fit for a given set of data. The points given will be plotted to see if there is a recognizable regression formed. In order to find the right regression equation‚ different regression equations will be tested with the data points provided. The process of finding the right equation and the testing of points will be provided. Each set of points and equations formed will include a graph. Once

perpendicularly from a long current-carrying wire. We found that there is a linear relationship between B/I and 1/r‚ which can be seen by the graph and is predicted by Ampere’s Law. The data from this experiment produced a plot of B/I vs 1/r with a regression with a r2of 0.9698‚ which indicates a highly linear relationship. Our slope was also only off by 0.0175% which indicates that this was a highly successful lab. There‚ as usual‚ are sources of error that can be seen. The magnetic field strength‚
