Answer:

The strength of magnetic field is $6.21 \times 10^{-5}$ T

Explanation:

Given:

Length of rod $l = 1.39$ m

Velocity $v = 3.37$ $\frac{m}{s}$

Induced emf $= 0.291 \times 10^{-3}$ V

According to the faraday's law

Induced emf = $Blv$

We have to find strength of the magnetic field,

$B = \frac{0.291 \times 10^{-3} }{1.39 \times3.37}$

$B = 6.21 \times 10^{-5}$ T

Therefore, the strength of magnetic field is $6.21 \times 10^{-5}$ T
