An Eagle, with a Wingspread Of $2.0 \mathrm {~m}$ , Flies Toward the North At

Short Answer

An eagle, with a wingspread of $2.0 \mathrm {~m}$ , flies toward the north at $8.0 \mathrm {~m} / \mathrm { s }$ in a region where the vertical component of the earth's magnetic field is $0.20 \times 10 ^ { - 4 } \mathrm {~T}$ . What emf would be developed between the eagle's wing tips? (It has been speculated that this phenomenon could play a role in the navigation of birds, but the effect is too small, in all likelihood.)
