A horizontal straight wire5 mlong extending from east to west falling freely at right angle to horizontal component of earth's magnetic field0.60×10-4 Wb m-2. The instantaneous value of emf induced in the wire when its velocity is10 m s-1is _______×10-3 V.

Answer:
3.00
Solution:

Horizontal component of earth's magnetic field, 

BH=0.60×10-4 Wb m-2.

Induced emf e=BHv

=0.60×10-4×10×5

=3×10-3 V
