If a magnetic particle is split quantum mechanically so that one component passes to one side, say the left, of the tube, while the other passes to the right. Although the magnetic field is zero outside the tube(cone), the vector potential associated with the field is not zero. The two components of the electron would acquire different phases due to their interaction with the vector potential - even though the field itself was zero - and that the difference between these phases could be detected via interference such as aluminum. The matter would not deform, liquify, or vaporize without alot of teslas ( really huge amount ) But i have seen frogs float in the air from doing this . Dr. Andre Geim of the University of Nijmegen in the Netherlands led the experiments, which were carried out using a giant superconducting magnet. The device creates a magnetic field that slightly distorts the orbits of the electrons in the atoms of any object placed in its path. The force generated was strong enough to make a frog float freely until it wriggled its way out of the field. The frog is being hailed as the first living creature ever to experience levitation. In technical terms, this floating effect derives from molecular diamagnetism, a very weak magnetic force possessed by all matter. Molecular diamagnetism has only a tiny fraction of the strength of ferro- magnetism, the force that holds magnets to your refrigerator, and it is repulsive rather than attractive. Any object placed into an adequately powerful magnetic field will thus repel away from the source. Hope this helps Thanks Brian D. Prater Cavetronics R&D labs
