Solving time: 2 mins

A square loop of side $20 cm$ and resistance $1Ω$ is moved towards right a constant speed $v_{0}$ . The right arm of the loop is in a uniform magnetic field of $5 T$ . The field is perpendicular to the plane of the plane, of loop and is going into it. The loop is connected to a network of resistor each of value $4Ω$ . What should be the value of vo so that a steady current of $2 mA$ flows in the loop?

\frac{B ℓ V}{R _{e q}} = 200 m A V = \frac{200 m A \times R e q}{B ℓ} = \frac{200 \times 1 0 ^{- 3} \times 5}{5 \times ( .2 )} = 1 m / s
