o. This step is to provide you with practice in graphing and in presenting data. Table o lists inductance data for 16 different coils wound on identical iron cores. There are three variables in this problem: the length of the coil (1) given in centimeters (cm), the number of turns, N, and the inductance, L, given in millihenrys (mH). Since there are three variables, we will hold one constant and plot the data using the remaining two variables. This procedure shows how one variable relates to the other. Start by plotting the inductance for coils that have 400 turns (last column) as a function of the length (first column). Inductance should be on the Y axis and length on the X axis.
