MetMo Eddy: A Desk Toy That Defies Gravity
Experience the mesmerizing physics of eddy currents in your hand.
1The Science Behind Eddy
MetMo Eddy is a palm-sized copper cylinder that showcases the physics of eddy currents. When a magnet drops through the tube, it generates electrical currents in the copper, creating a magnetic field that opposes the fall. This effect, first observed by physicist Léon Foucault in 1855, slows the magnet’s descent, making gravity appear to pause. The toy requires no batteries, relying solely on the interaction between the magnet and copper.
2Precision Engineering
Each MetMo Eddy tube is CNC-machined from ultra-high-purity, lead-free copper to exacting tolerances. The inner wall is designed to sit close to the magnet without touching it, maximizing the eddy current effect. This precision ensures a smooth, slow descent of the magnet. The tube’s rose-toned glow and polished finish add aesthetic appeal, making it a standout desk object.
3Design Details
MetMo Eddy is designed and finished by hand in the UK. It stands just under 3 inches tall, weighs 3 ounces, and features knurled caps for easy handling. The smooth, brushed middle section contrasts with the textured caps, highlighting the craftsmanship. A passivated surface finish slows oxidation, keeping the copper looking freshly machined for longer without constant polishing.
4Silent Operation
One of Eddy’s standout features is its silent operation. Unlike many desk toys, it produces no clicks, rattles, or thuds when the magnet reaches the bottom. This silence enhances its appeal as a calming, distraction-free object. The elongated window cut into the tube allows users to watch the magnet’s descent, adding to the visual intrigue.
5Versatile Use
MetMo Eddy isn’t just a fidget toy; it’s a five-second reset button for your day. Its compact size and one-handed flip make it easy to use between emails or during calls. The toy’s design encourages repeated use, with the eddy current effect remaining mesmerizing even after multiple drops. It’s both a functional tool and a decorative piece.
6Customizable Experience
Users can unscrew the end caps to adjust the magnet’s drop or thread two tubes together for a longer descent. These modifications don’t alter the eddy current effect but add variety to the experience. The toy’s simplicity and adaptability make it suitable for both casual users and physics enthusiasts.
7Aesthetic Appeal
Copper’s conductivity and warm glow make it the ideal material for Eddy. It generates a stronger eddy current response than alternatives like aluminum or steel, resulting in a more pronounced slowdown. The tube’s polished finish and rose-toned hue make it visually appealing, blending seamlessly with modern desk setups.
8Lasting Impression
MetMo Eddy leaves a lasting impression on users, thanks to its combination of physics, design, and craftsmanship. The toy’s ability to consistently captivate users, even after repeated use, speaks to the strength of its underlying concept. It’s a conversation starter and a testament to the beauty of scientific principles in everyday objects.
