Question 43
Easy

A researcher investigates how the magnetic flux density, BBB, of a powerful neodymium magnet varies with distance, ddd, from its magnetic centre along its longitudinal axis.

The grid in Figure 1 shows the majority of the researcher's results plotted as a scatter diagram.

The table in Figure 2 displays two additional measurement data points.
