Problem

A futuristic hoverboard uses electromagnetic levitation to float above a conducting track. The hoverboard contains a circular coil of wire with

N = 200

turns and radius

r = 15\;\text{cm}

. When hovering, a steady current of

I = 8.0\;\text{A}

flows through the coil, creating a magnetic dipole. The conducting track below acts like a mirror for magnetic fields, effectively creating an image dipole at the same distance below the track surface. If the coil's center is

h = 5.0\;\text{cm}

above the track surface, find the magnetic field strength at the center of the hoverboard's coil due to the image dipole below the track.
