Electromagnetic Induction

Question

An aeroplane is flying horizontally from west to east with a velocity of 900 km/hour. Calculate the potential difference developed between the ends of its wings having a span of 20 m. The horizontal component of the Earth’s magnetic field is 5 × 10^–4 T and the angle of dip is 30°.

Solution

e = B_v.V.l

= $5 x 10^{- 4} \sin 30 x 900 x \frac{5}{18} x 20 = 1.25 V$
