A metallic conductor of length 1 m rotates in a vertical plane parallel to east-west direction about one of its end with angular velocity 5 rad s –1 . If the horizontal component of earth’s magnetic field is 0.2 × 10 –4 T, then emf induced between the two ends of the conductor is:

1. 5 μ V
2. 50 μ V
3. 5 mV
4. 50 mV

Correct answer: 50 μ V
