The current carrying wire and the rod \( A B \) are in same plane. The rod moves parallel to the wire with a velocity v. Which one of the following statement is true about induced emf in the rod?
-(1) End \( A \) will be at lower potential with respect to \( B \)
(2) \( A \) and \( B \) will be at same potential
- (3) There will be no induced emf in the rod
(4) Potential at \( A \) will be higher than that at \( B \)
