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.

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
