It's a steel ball. When a metal such as iron or steel is brought near a magnet, magnetism is INDUCED in it, i.e haphazard domains arrange, and the metal is always ATTRACTED. Thus, the steel ball, which is unmagnetised, will become magnetised, i.e will be ATTRACTED to the N pole.

ok the steel ball rolled is attracted to the magnet so it deflects upwards .. however u may ask why didnt it 'stick' the magnet .. probably because the ball is pushed with a force which overcomes the strength of the magnetic field ..

Yes, in other words, the force applied in the 'push' is greater than the pull of the magnet, thus it IS ATTRACTED, however continues forward motion, but the attraction creates deviation of path, i.e deflecting in towards the N.
