Motional EMF

A straight line conductor of length 0.4 m is moved with a speed of $7.0$ ms $^{-1}$ perpendicular to magnetic field of intensity $0.8$ Wb m $^{-2}$ . The induced e.m.f. across the conductor is

Show answer and solution

Answer: (a)

Motional emf $\varepsilon = Blv$ .
$\varepsilon = 0.8 \times 0.4 \times 7.0 = 2.24$ V
So the answer is (a) $2.24$ V.
