Getting a magnetic field to balance on another magnetic field is about as easy as balancing a bowling ball on the tip of an ink pen. With a little help from an Arduino mega, however, [EmmaSong] was… ...

The Hall effect sensor monitors the field of the permanent magnet and uses that information to modulate the magnetic field of the electromagnet, with everything being crunched by the Arduino.

Diamagnetic Levitation Systems and Applications Publication Trend The graph below shows the total number of publications each year in Diamagnetic Levitation Systems and Applications.

Caption Magnetic levitation demonstrated using a Dremel tool spinning a magnet at 266 Hz. The rotor magnet is 7x7x7 mm3 and the floater magnet is 6x6x6 mm3.

Harvard researchers develop a system to orientate small objects in any direction using magnetic levitation.
