Permanent magnets
Motion in a magnetic field

A steel ball is released on a descent, moving in a rectilinear motion on an horizontal plane. If the ball passes close to the pole of a magnet, its trajectory is deflected. Its velocity changes and this indicates the action of the force of the magnet-sphere interaction. The trajectory described by the steel ball is completely different from the magnetic field lines produced by the magnet
