Interpret data relating to the strength of a magnet at various distances. Electromagnetic induction

A student measures the magnetic field strength of a bar magnet at varying distances along its axial line. The data collected is plotted on a graph showing that as distance increases from 2.0 cm to 10.0 cm, the field strength decreases from 48 mT to 1.0 mT, with the curve becoming progressively flatter. What happens to the gradient of the magnetic field strength versus distance curve as the distance from the magnet increases from 2.0 cm to 10.0 cm?

A student investigates how the magnetic field strength of a bar magnet varies with distance. She places a magnetic field sensor at different distances from the north pole of the magnet along its central axis and records the data shown in the table below. Which statement best describes the pattern shown in the data as the distance from the magnet increases from 2.0 cm to 10.0 cm?

A student measures the magnetic field strength at various distances from a bar magnet using a Hall probe. The graph shows the relationship between magnetic field strength and distance from the magnet's north pole along its axial line. At what distance from the magnet is the field strength approximately 40 mT?
