DetailsThe magnetic coil accelerates the ball because the ball is ferromagnetic - if you put an external magnetic field, the ball is magnetized in such a way that it is attracted to that magnetic field, no matter what direction the field points. One detail you might have missed is that the coil has to turn off before the ball is done going through it.
