1. A magnetic levitation system comprising:
a first cylinder-shaped magnet;
a second cylinder-shaped magnet coaxially aligned with the first cylinder-shaped magnet;
a first cavity coaxially aligned with and formed in the first cylinder-shaped magnet; and
a container configured to hold a paramagnetic solution;
wherein the surfaces of like polarity of the first and second cylinder-shaped magnets are parallel to each other and face each other to result in a linear, axially symmetric magnetic field between the first and the second magnets; and
wherein the container is at least partially disposed between the first and the second cylinder-shaped magnets.
