Magnetic levitation

An experiment with off-the-shelf components uses a magnet glued to the end of a rotary multitool. Its rotation causes a second magnet to levitate millimeters away from the first one.[1]
This article is about the physical phenomenon. For the form of transportation, see Maglev.
Magnetic levitation can be stabilised using different techniques; here rotation (spin) is used

Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces.[2]

The two primary issues involved in magnetic levitation are lifting forces: providing an upward force sufficient to counteract gravity, and stability: ensuring that the system does not spontaneously slide or flip into a configuration where the lift is neutralized.

Magnetic levitation is used for maglev trains, contactless melting, magnetic bearings, and for product display purposes.
