A horizontal straight wire 5 m long extending from east to west falling freely at right angle to horizontal component of earth's magnetic field 0 . 60 × 10 - 4 Wb m - 2 . The instantaneous value of emf induced in the wire when its velocity is 10 m s - 1 is _______ × 10 - 3 V .

Correct answer

0

Step-by-step solution

Horizontal component of earth's magnetic field, B H = 0 . 60 × 10 - 4 Wb m - 2 . Induced emf e = B H v ℓ = 0 . 60 × 10 - 4 × 10 × 5 = 3 × 10 - 3 V
