Magnetic levitation using diamagnetism: Mechanism, applications
As a typical contact-free manipulation technique that removes friction and contamination risk, levitation has gradually become a preferred candidate for various applications. Magnetic levitation using diamagnetism, beyond Earnshaw''s theorem, is a kind of passive stable levitation that can be achieved at normal temperatures with no
Design of a stabilised flywheel unit for efficient energy storage
It is not widely recognised that there is not a single principle of generating the magnetic lifting force. There are two configurations. Generally known - more or less - is the Maxwell electrodynamic force, Fig. 1 (a), attracting the a ferromagnetic object to a core of an electromagnet. The other case is the Lorentz force [14, 15], schematically
Revolutionizing gravity-free tech: Novel material propels magnetic
The primary issue is a phenomenon known as "eddy damping," which causes the platform to gradually lose energy. Think of it as the air resistance slowing down a spinning top. OIST scientists aimed to create a platform with infinite energy storage capacity. This holds great potential for the development of novel force and gravity sensors.

Magnetic Levitation
One form of levitation needs an active energy input to sustain levitation and the other needs cryogenic temperatures to achieve levitation. A little known form of magnetic levitation called diamagnetic levitation is the only form of passive levitation that is possible at room temperature.

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.
Magnetic Levitation: School Experiment
Magnetic levitation uses magnetism to suspend an object in the air. It counters gravity and any other vertical acceleration or deceleration factors. Two primary forces are involved. The first lifts the object with sufficient force to counter gravity. The second ensures stability, so it cannot slide sideways to neutralize the lift.
Magnetic levitation by rotation
Hence, this type of magnetic levitation does not rely on gravity as a balancing force to achieve an equilibrium position. Based on theoretical arguments and a numerical model, we show that a constant, vertical field and eddy-current enhanced damping is sufficient 1Department of Energy Conversion and Storage, Technical University of Denmark
Maglev | Facts, Operation, & Systems | Britannica
6 · Maglevs incorporate a basic fact about magnetic forces—like magnetic poles repel each other, and opposite magnetic poles attract each other—to lift, propel, and guide a vehicle over a track (or guideway). Maglev propulsion and levitation may involve the use of superconducting materials, electromagnets, diamagnets, and rare-earth magnets.

Electromagnetic suspension ( EMS) is the magnetic levitation of an object achieved by constantly altering the strength of a magnetic field produced by electromagnets using a feedback loop. In most cases the levitation effect is mostly due to permanent magnets as they have no power dissipation, with electromagnets only used to stabilise the effect.
