Question

Adjust plane is travelling towards west at a speed of 1800 km per hour estimate voltage difference developed between the ends of the wing having a span of 25 m if the Earth's magnetic field at the location has a magnitude of 5* 10^-4 T and dip angle 30 degree . How will the voltage developed be affected if the jet changes its direction from west to North

Answer 1

Dear student
$$\begin{gathered} a)Emfdevelopedwhiletravellingtowardswest \\ E=B_{vertical}\times v\times l \\ \sin 30=\frac{B_V}{B} \\ \frac{1}{2}=\frac{B_V}{B}=\frac{B_V}{5\times {10}^{-4}} \\ {B}_V=2.5\times {10}^{-4}T \\ E=B_{vertical}\times v\times l=2.5\times {10}^{-4}\times 500\times 25=25\times 25\times 5\times {10}^{-3}=\frac{25}{8}volt \\ E=3.125volt \\ b)whentheplanewillflytowardsnorththanalsotheemfisduetoverticalcomponentoftheearthmagneticfield.Soemfinducedremainssame. \\ E=3.125volt \\ Regards \end{gathered}$$
