Problem

A hummingbird has tiny magnetite crystals in its beak that act like microscopic compass needles, helping it navigate using Earth's magnetic field. During migration, the bird flies horizontally at a constant speed of v=8.0  m/sv = 8.0\;\text{m/s} through a region where Earth's magnetic field has a vertical component of B=5.0×10−5  TB = 5.0 \times 10^{-5}\;\text{T} pointing downward. As the bird moves through this field, a motional EMF is induced across its outstretched wings. If the bird's wingspan is L=12  cmL = 12\;\text{cm}, what is the magnitude of the motional EMF induced across its wings?
