Electric Charges And Fields

Question

A jet plane is travelling west at 450 m/s. If the horizontal component of earth's magnetic field at that place is 4 x 10^–4 tesla and the angle of dip is 30°, find the emf induced between the ends of wings having a span of 30 m.

Solution

Here,
Velocity of jet plane, v = 450 m/s
Length of the jet wing, l = 30 m
Horizontal component of Earth's magnetic field, B = 4 x 10^–4 T
Angle of dip, θ = 30°

Using the formula for induced e.m.f we have,

Induced e.m.f,

ε = B l ν \sin θ

= 4 \times 10^{- 4} \times 30 \times 450 = 5.4 V

The direction of the wing does not affect this e.m.f.
