As shown in the figure, a straight wire carries a steady current I. A metal bar is in contact with a pair of rails and is in upward motion with velocity of magnitude ν. The polarity of the induced emf in terminals X and Y is
• X is positive and Y is negative.
• X and Y are at the same potential.
• Y is positive and X is negative.
• X is positive and Y is negative.
• X and Y are at the same potential.
• Y is positive and X is negative.
