## Compute the emf induced between the ends of the wings, Physics

Assignment Help:

Q. An aircraft having awing span of 20.48 m flies at a speed of 40 ms-1. If the vertical component of the earth's magnetic field is 2 X 10-5 T, compute the emf induced between the ends of the wings.

Data:   l = 20.48 m; v = 40 ms-1; B = 2 × 10-5T; e = ?

Solution:         e = - B l v = - 2 × 10-5 × 20.48 × 40

e = - 0.0164 volt

Negative sign is due to Lenz law.
