Magnetic levitation is used to make many things, from trains to lamps, float, but it usually requires a power source. Scientists in Japan does not require an external power supplydeveloped a floating platform made of ordinary graphite material. This means we may see household items floating without energy.
Household objects floating in the air: Energy-free levitation
This new discovery was made possible thanks to the naturally high diamagnetic properties of graphite. Levitated graphite household items can float on magnets for a short time, but electric currents passing through the graphite cause energy loss and cause the levitated object to fall.
to this event eddy damping It is said. To solve this problem and pave the way for floating household items, researchers used electrically insulating graphite particles. They coated it with silica and then silica-coated graphite particles with wax mix and approx. 1 cm2 They made it into slabs of different sizes.
It’s building itself! Here is the wind turbine that will provide cheap energy
Self-building wind turbine is coming thanks to WindSpider cranes, a new technology that will revolutionize cheap energy.
During this process, graphite retained its diamagnetic properties and the silica coating prevented energy loss. This new platform system could lead to new types of sensors that measure force, acceleration and gravity. Another version, for more sensitive quantum sensors, uses a feedback magnetic force that constantly corrects vertical movements of the platform.
However, this version has the disadvantage that it requires an external power source. This research Applied Physics Letters It was published in the magazine. The levitated graphite composite plate can be seen in the video below.

It should be noted that the levitation platform made of graphite can currently only levitate small, lightweight objects and requires a certain magnetic infrastructure.
This technology can be used to keep household items in the air by producing floating household items according to this technology. Additionally, factors such as safety, cost, and practical applicability may also affect the widespread use of such applications.
This innovative technology could enable new applications in many different fields as a power-free way of magnetic levitation.
