# A jet plane of wing span 20 m is travelling towards west at a speed of 400 ms-1. If the earth’s total magnetic field is 4×10-4 T and dip angle is 30 degrees, at that place, what is the voltage difference developed across the ends of the wing ?

Given: B= 4 x 10-4 T
l = 20 m
v  = 400m/s
$\Theta$ = 30o
e= dV =?
formula : e = Blv sin$\Theta$
= 4 x 10^-4 x 20 x 400 x sin 30
= 1.6V
