rod length L

movin wid velocity V

magnetic field perpendicular 2 d plane of d paper

now it is said that a force due 2 magnetic field acts on d e- inside it due 2 which d e-s moves 2 one end of d rod

here d angle between V & B is 90 therefore d e- should move in circular path

thus it should not reach d end then how is d polarity created
