Electromagnetic Induction Problem : Help needed

    Electromagnetic Induction Problem : Help needed
    The flux density B in a region between the pole faces of a horse shoe magnet is 0.5T directed vertically downward. Find the emf induced in a straight wire 5cm long, perpendicular to B when it is moved in a direction at an angle of 60 degrees with the horizontal with a speed of 100 cm/s...

    Answer in book= 0.0125 V

    I'm getting 0.022 V by applying the formula: emf=vBLsin60
    It's supposed to be quite straightforward, what am i missing then?

    the angle 60 is measured to the horizontal, so the magnetic field is at angle of 30 degrees to the wire.
