You've seen it. A sculpture floating silently in mid-air, rotating slowly without any wires or supports. It looks like a magic trick — but the science behind magnetic levitation is surprisingly elegant. Here's exactly how it works, and why Leviou's pieces stay suspended 24 hours a day.
What is magnetic levitation?
Magnetic levitation — often shortened to maglev — is the process of suspending an object in the air using magnetic forces alone, with no physical contact. The object floats freely, defying gravity through a precise balance of attracting and repelling magnetic fields.
While the concept has been used in engineering applications like high-speed trains and frictionless bearings, it has more recently made its way into the world of home decor and art — most visibly in levitating magnetic displays like those made by Leviou.
The basic physics: why magnets can levitate objects
Every magnet has two poles — north and south. Like poles repel each other, while opposite poles attract. In a simple setup, you could balance one magnet above another by aligning them so the repelling force exactly counteracts gravity. The problem? This kind of passive magnetic levitation is inherently unstable. Any slight tilt and the object shoots sideways and falls.
This is described by Earnshaw's Theorem, a fundamental principle in physics that proves a static arrangement of magnets alone cannot produce stable levitation. Something more sophisticated is needed.
How Leviou's levitation actually works: active electromagnetic stabilisation
Leviou pieces use a technique called active electromagnetic levitation. Here's what's happening inside the base:
- A powerful neodymium magnet is embedded in the floating object — the sculpture itself.
- An electromagnet inside the base generates an upward magnetic field strong enough to support the object's weight.
- Hall effect sensors inside the base constantly monitor the position of the floating magnet — thousands of times per second.
- A microcontroller (control circuit) processes the sensor readings in real time and adjusts the current flowing through the electromagnet to keep the object in the exact same position.
If the sculpture drifts even a fraction of a millimetre downward, the controller increases the electromagnetic force to push it back up. If it drifts upward, it reduces it. This feedback loop runs continuously and silently, keeping the piece hovering at a fixed point in space with remarkable precision.
This is the same fundamental technology used in maglev trains — just miniaturised into a sleek, whisper-quiet base that fits on your desk or shelf.
Why does it rotate?
The slow, continuous rotation you see in Leviou pieces is produced by a secondary system — a small rotating magnetic field generated in the base. This field interacts with the permanent magnet in the sculpture and induces a gentle spin. The rotation speed is carefully tuned to feel organic and meditative rather than mechanical — typically one full rotation every 10 to 20 seconds.
Because there is zero physical contact between the sculpture and the base, there is no friction, no wear, and no noise. The piece can rotate indefinitely.
What makes neodymium magnets special?
Neodymium magnets — the type used in Leviou sculptures — are the strongest type of permanent magnet available. Made from an alloy of neodymium, iron, and boron, they produce an exceptionally powerful magnetic field relative to their size. This is what allows a compact, elegant base to levitate a solid resin sculpture weighing several hundred grams while remaining small enough to sit unobtrusively on a surface.
Is it safe to have a levitating display at home?
Yes. The magnetic field produced by a levitating display is localised and not harmful under normal conditions. The main precautions are the same as with any strong magnet: keep the base away from credit cards, pacemakers, and other magnetic-sensitive devices, and keep out of reach of small children. Beyond that, a Leviou piece can run continuously and safely as an always-on feature of your space.
