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
