Question 23
Easy

A student investigates how the magnetic flux density at the center of a solenoid changes as the current through the coil is varied.

The results of this investigation are shown in Figure 1.

A graph showing magnetic flux density in millitesla (mT) on the y-axis plotted against current in amperes (A) on the x-axis.

Describe the relationship between the magnetic flux density and the current.
