Question 2

An eagle, with a wingspread of 2.0 m, flies due North at 8.0 m/s in a region where the vertical component of the earth's magnetic field is 0.2 10-4 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.)
