Graphene is a single layer of carbon atoms arranged in a hexagonal lattice, which makes it incredibly strong and lightweight compared to other materials. However, what sets graphene apart from other materials is its unique magnetic properties.

One property that allows graphene to levitate over the four neodymium magnets is its high electrical conductivity. Graphene has a resistivity of only about 1.6 x 10^-6 ohms cm^2/degC, while other materials such as iron have a resistance of several times that amount. This means that when graphene is connected to a power source, it can conduct electricity quickly and efficiently without losing energy.
Another important property of graphene is its ability to form strong, permanent bonds with other materials. Unlike other materials, which often lose their shape when subjected to stress or pressure, graphene maintains its shape indefinitely. This property makes graphene an ideal material for use in flexible electronics, where small changes in shape can affect the performance of electronic devices.
In addition to its electrical and mechanical properties, graphene also has unique magnetic properties. When graphene is treated with a magnetic field, it can become paramagnetic, meaning that it can change its direction of motion based on the strength of the magnetic field. This property has applications in fields such as magnetic resonance imaging (MRI) and quantum computing.
The phenomenon of graphene levitating over the four neodymium magnets described above was first observed in 2014 by researchers at the University of California, Berkeley. The scientists found that when they applied a strong magnetic field to graphene, it began to levitate in mid-air, even though there were no external forces acting on it. They attribute this phenomenon to the unique electronic and mechanical properties of graphene.

In conclusion, graphene’s unique properties make it a promising material for various applications. Its high electrical conductivity, ability to form strong bonds with other materials, and unique magnetic properties make it an ideal material for use in flexible electronics and other fields. While there is still much research to be done to fully understand these properties, the discovery of graphene levitation over the four neodymium magnets is a significant milestone in the field of materials science.
