A metal rod of length 50 cm is held vertically and moved with a velocity of \(10 {~m} / {s}\) towards east. The horizontal component of the Earth's magnetic field at the place is \(0 \cdot 4 {G}\) . The emf induced across the ends of the rod is:
- 0.1 mV
- 0.2 mV
- 0.8 mV
- 1.6 mV
Answer
(B) 0.2 mV
