  • A horizontal straight wire 10 m long extending from east to west is falling with a speed of 5 point 0 m s ^- 1.

Q6.7 (a) A horizontal straight wire 10m  long extending from east to west isfalling with a speed of 5.0 m\: s^{-1}, at right angles to the horizontal component of the earth’s magnetic field, 0.30\times 10^{-4}\: wb\: m^{-2}.

What is the instantaneous value of the emf induced in the wire?

Given

Length of the wire l=10m

Speed of the wire v=5m/s

The magnetic field of the earth B=0.3*10^{-4}Wbm^{-2}

Now,

The instantaneous value of induced emf :

e=Blv=0.3*10^{-4}*10*5=1.5*10^{-3}

Hence instantaneous emf induce is 1.5*10^{-3}.
