6.10 A jet plane is travelling towards west at a speed of 1800 km/h. What is the voltage difference developed between the ends of the wing having a span of 25 m, if the Earth’s magnetic field at the location has a magnitude of 5 × 10–4 T and the dip angle is 30°.

6.10 Speed of the jet plane, v = 1800 km/h = 500 m/s
Wing span, l = 25 m
Earth’s magnetic field, B = 5 T
Dip angle, = 30
The vertical component of the earth’s magnetic field, = B = 5 = 2.5 T
Voltage difference between the ends of the wing can be calculated as
e = = 2.5 = 3.125 V
