A levitation apparatus is a device designed to lift objects off the ground without any physical support. This technology often uses magnetic fields, air pressure, or sound waves to create a force that counteracts gravity. Common examples include magnetic levitation trains, which glide above tracks, and small devices that can levitate objects for demonstrations. These apparatuses can be found in various applications, from scientific experiments to entertainment. For instance, magnetic levitation is used in maglev trains for efficient transportation, while acoustic levitation can be used in laboratories to manipulate small particles without contact.
