Question

A horizontal straight wire 5m long extending from east to west falling freely at right angle to horizontal component of earth's magnetic field 0.60 10^-4 Wbm^-2. The instantaneous value of emf induced in the wire when its velocity is 10 ms^-1 is____ 10^-3V

Accepted Answer

Correct answer: 3. (3) B_H=0.60 10^-4 Wb/m^2 Induced emf e=B_Hvl =0.60 10^-4 10 5 =3 10^-3 V

$A horizontal straight wire 5 m long extending from east to west falling freely at right angle to horizontal component of earth's magnetic field 0.60 \times 10^{- 4} Wbm^{- 2} . The instantaneous value of emf induced in the wire when its velocity is 10 ms^{- 1} is____\times 10^{- 3} V$
