A metal airplane flies horizontally at 200. m/s where the Earth's magnetic field
is vertical and is 45.0 μT. If the wingspan is 25.0 meters:
(a) what emf is induced across the wings?
(b) what wingspan would produce 1.0 volt emf?
(c) The plane reverses direction. Does the polarity of the wingtip emf change, i.e., if the left wing was positive, does it now become negative?
