Question
A 10 m wide spacecraft moves through the inter steller space at a speed 3×107ms−1. A magnetic foeld B = 3×10−10 T exicts in the space in a direction perpendicular to the plane of motion. Treating the spacecraft as a cond uctor, calculate the emf induced across its width.

Solution
Here 1 = 10 m, v = 3×107 m/s,
B = 3×10−10 T.
Motional emf = Bvl
= 3×10−10×3×107×10
= 9×10−2 = 0.09 V.
Here 1 = 10 m, v = 3×107 m/s,
B = 3×10−10 T.
Motional emf = Bvl
= 3×10−10×3×107×10
= 9×10−2 = 0.09 V.
