    Answer:As the bar moves upward through the constant magnet

    ic field region, the area of the loop decreases, so

    the flux through the loop

    decreases. By Lenz’s law, any induced current will

    tend to oppose the decrease. Using right hand rule

    we know that magnetic field

    inside the loop due to a ccw current comes out of t

    he plane. Therefore a ccw current will create a str

    onger magnetic field inside

    the loop, tending to increase the flux.
