Problem

A miniature bar magnet produces a magnetic field of

50\,\mu\text{T}

at a distance of

5.0\,\text{cm}

along its axis. How far from the magnet’s center (along the same axis) must you move so that the field magnitude drops to

2.0\,\mu\text{T}

? Give your answer to two significant figures.
