Question
To generate the data shown at the right, the dipole magnet was moved closer to the sensor (holding for 10-20 seconds at each distance). The magnet was then moved back away from the sensor in a similar fashion. This provided two data points at each distance (except the closest) to be averaged. Each data point was corrected for the background magnetic field measured at 0.5 meters (no change observed at longer distances). The absolute values of the corrected field are given in the table.Use the data provided below to determine the dependence of the magnetic field on distance, based on a linear trendline.
