Question

A 10 m long horizontal wire extends from North East to South West. It is falling with a speed of 5.0 ms^–1, at right angles to the horizontal component of the earth's magnetic field of 0.3 $ \times $ 10^–4 Wb/m². The value of the induced emf in wire is :

0.3 $ \times $ 10^–3 V

2.5 $ \times $ 10^–3 V

1.5 $ \times $ 10^–3 V

1.1 $ \times $ 10^–3 V
