    Answer:

    The required emf moved across the wire is zero

    Explanation:

    For a moving charge particle, the magnetic force can be determined by using the formula;

    \varepsilon = Bvlsin \theta

    since the wire moves in parallel, the angle \theta between magnetic field and velocity = 0°

    B = 0.500 T

    v = 1.50 m/s

    l = 0.200 m

    \varepsilon = (0.500  \ T )(1.50 \ m/s) \times (0.200 \ m)\times sin (0)

    \varepsilon = 0.15\times sin (0)

    \varepsilon = 0
