Figure 1 shows how the magnetic field strength varies with distance from a straight current-carrying wire.

Figure 1: Graph of magnetic field strength in microtesla (µT) on the vertical axis against distance from the wire in centimeters (cm) on the horizontal axis.

Use the graph in Figure 1 to calculate the decrease in magnetic field strength when the distance from the wire increases from 2 cm to 6 cm.
