After seeing the unusual way in which magnets interact with copper, NightHawkInLight explores whether an electromagnetically-generated force field in copper could stop or slow a magnetic projectile in mid-flight.
The Moon camera has a base that allows for magnetic levitation and wireless charging. But it’s more than a floating eye. It can rotate itself towards a source of sound, and act as a home automation controller. It even has an IR blaster to control older appliances.
We’ve seen several objects that use magnetic levitation. This floating pillow lets you show off the precious items that you already own. It’s strong enough to lift jewelry, watches and other small items. The base comes in wired and wireless models, and three colors.
Students from the Ithaca College Low Temperature Physics Lab created a neat version of a quantum levitation track. It still uses supercooling and magnets to work its magic, but adds a fun (and literal) twist to by running its course around a triple-twist Möbius Strip.
The process of sandwiching oil and ferrofluid between sheets of glass is messy to say the least, but the result is amazing – the ability actually view the radiating fields created by magnets placed on the surface of the glass. Magnetic Games shows us how its done.
For Inventables’ fidget spinner challenge, Giaco Whatever decided to see if he could make one that could float in mid air. After a bunch of experimentation, he was able to get it to work by placing it between two opposing magnetic fields, and spinning it for stabilization.
Beyond its liquid properties, the other cool thing about mercury is that it’s magnetic. Roobert33 shows how electromagnets can be used to change the direction that mercury flows in. It would be cool to build an Escher-style fountain that flows uphill with this method.
This unique wall or table clock uses the power of magnetic levitation to float its hour hand (er, hour sphere) off its surface, creating a dramatic and minimal display as it casts a shadow on the wooden surface beneath. Want the exact time? An LED matrix display hides beneath the wood.
ThinkGeek presents a unique take on the traditional hourglass with a version that’s filled with magnetic filings instead of sand. As the tiny metal particles fall to the bottom, they stand up forming unusual organic shapes. Keep in mind that it’s not for actual timekeeping.
