Answer:

83.847519 mV

Explanation:

B = Magnetic field strength = 7.11 mT

L = Length of steel rod = 99.1 cm

v = Velocity of steel rod = 11.9 m/s

The induced electro motive force is given by

$E=BLV\\\Rightarrow E=7.11\times 10^{-3}\times 0.991\times 11.9\\\Rightarrow E=0.083847519\ V=83.847519\ mV$

The magnitude of the EMF induced between the ends of the rod is 83.847519 mV
