The magnet is placed over a super conducting material. Because super conductors conduct electricity with zero resistance, it repels the magnet making it float. The super conductor is usually a piece of YBa2Cu3O7 cooled to below 92 degrees kelvin. At this temperature, the substance changes state from a solid to a bose-einstein condensate and is a super conductor.

BeauRing magnets can appear to "float" due to the repelling force created when two magnets with the same pole orientation are placed facing each other. This force counteracts the effect of gravity, causing the ring magnet to levitate. The stability and balance of the floating ring magnet can be influenced by the strength of the magnets and the distance between them.

How many types of magnets are there?
none
What are the types of magnets?
There are permanent magnets, which retain their magnetism once magnetized, and temporary magnets, which only exhibit magnetic properties when exposed to a magnetic field. Permanent magnets can be further classified into ferromagnetic, ferrimagnetic, and rare-earth magnets based on their composition and magnetic properties.
Are magnets metal?
No, magnets are not metal. Magnets are objects that produce a magnetic field, which can attract or repel certain types of metals, but they are typically made from materials like iron, nickel, or cobalt.
Why don't we use permanent magnets in electric bell?
Permanent magnets do not provide the flexibility to control the strength of the magnetic field, which is essential for regulating the vibration of the armature in an electric bell. Electromagnets, on the other hand, allow for the magnetic field strength to be easily adjusted by varying the current flowing through the wire, enabling precise control over the bell's operation.
Do magnets attract all metals?
No. Magnets do not attract gold, silver, aluminum, brass, copper or lead. Magnets will attract nickel and iron or steel.
