Question 282: Electromagnetic Induction

Question

An air craft of wing span $$40 \mathrm{~m}$$ files horizontally in earth's magnetic field $$5 	imes 10^{-5} \mathrm{~T}$$ at a speed of $$500 \mathrm{~m} / \mathrm{s}$$. The e.m.f. generated between the tips of the wings of the air craft is

Accepted Answer

The emf generated between the tips of the wings of the air craft is,
$$\begin{aligned}
& \varepsilon=\mathrm{Blv} \
& \varepsilon=5 	imes 10^{-5} 	imes 40 	imes 500 \
& \varepsilon=1 \mathrm{~V}
\end{aligned}$$
