Abstract
Previous papers about diamagnetic levitation describe using vertical magnet configurations. At least one paper has mentioned a horizontal configuration using two permanent or electromagnets. However, none gives any quantitative analysis for the horizontal configuration. In addition none seems to have considered levitating a magnet at other angles, cases between these two configurations. The existence of these two extremes suggests that one possibly could levitate a magnet at other angles between 0 (vertical) to p/2 radians (horizontal). This paper explores one a configuration of two permanent suspending magnets for levitating a magnet using a horizontal configuration as well as another configuration using a permanent and electromagnet combo (allows variable field strength) for levitating magnets at angles not equal to p/2. This was done numerically by evaluating the basic equations and looking for equilibrium points where net forces and moments on a levitating magnet are zero. For all cases considered here, the two axes of the two suspending magnets were always directly aligned with each other. For a range of angles near p/2 radians, one can stably levitate a magnet parallel to the suspending magnets by using a permanent and electromagnet combo.
