(C) To determine the direction of the magnetic field,we use Fleming's Right-Hand Rule.According to Fleming's Right-Hand Rule,if we stretch the thumb,forefinger,and middle finger of the right hand mutually perpendicular to each other:$1$. The thumb points in the direction of the motion of the conductor $(v)$.$2$. The forefinger points in the direction of the magnetic field $(B)$.$3$. The middle finger points in the direction of the induced current $(i)$.In the given figure,the conductor is moving towards the right (thumb points right) and the induced current is upwards (middle finger points up).By aligning the right hand such that the thumb points right and the middle finger points up,the forefinger will point into the plane of the paper.Therefore,the magnetic field is perpendicular to the plane of the paper and directed downwards (into the plane).

$A$ conducting wire is moving towards the right in a magnetic field $B$. The direction of the induced current $i$ in the wire is shown in the figure. The direction of the magnetic field will be
