1. The problem statement, all variables and given/known data I have been working on a lab report recently in which I took some data and then further used this data to gather results. I was plotting magnetic flux density as a function of current, this turned out to be an exponential saturation curve. I plotted this curve using a package at university. My question is, do I use my original data points to calculate my results, or do I use the data that the non-linear fit gives me? 2. Relevant equations Y=b1*(1-exp(-b2*x)) -> My equation for the linear fit 3. The attempt at a solution I have tried both, the results from the equation seem to give results closer to tabulated values; however I am wondering is this the correct way to go about the experiment.
