Answer
Fleming's right hand rule — Stretch the thumb, central finger and forefinger of your right hand mutually perpendicular to each other. If the forefinger indicates the direction of magnetic field and the thumb indicates the direction of motion of the conductor, then the central finger will indicate the direction of induced current.

Why does it become more difficult to move a magnet towards a coil when the number of turns in the coil has been increased ? (Hint : e.m.f. induced in the coil and hance the magnetic field induced by it, becomes more when the number of turns in the coil are increased. The stronger field induced opposes the motion of the magnet towards the coil)
