A jet plane is travelling west at 450m/sec. If the horizontal component of earth’s magnetic field at that place is 4 x 10 -4 T and angle of dip is 30. Find the emf induced between the ends of wings having span of 30m.

The wings of jet plane will cut the vertical component of earth’s magnetic field, so emf is induced across the wing. The vertical component of earth’s magnetic field.


V = H tan theta
V = 4 * 10^-4 * 1/ sqrt 3
 
Induced EMF = V *v* l
 
Now you can calculate.
