Magnetic levitation demonstrated using a Dremel tool spinning a magnet at 266 Hz. The rotor magnet is 7x7x7 mm3 and the floater magnet is 6x6x6 mm3. This video show the physics described in the work ...

Most of our readers are already going to be familiar with how electromagnets work — a current is induced (usually with a coil) in a ferrous core, and that current aligns the magnetic domains present ...

Who doesn’t love magnets? They’re functional, mysterious, and at the heart of nearly every electric motor. They can make objects appear to defy gravity or move on their own. If you’re like us, when ...

Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By overcoming the limitations of the well-known Halbach array, which works ...

Magnetic levitation (maglev) can create frictionless, efficient, far-out-sounding technologies. Here are some of the craziest uses that engineers and designers have dreamed up. Magnetic levitation ...

For three years as an undergraduate physics student performing at science magic shows and open houses, I convinced students (and sometimes their parents) that I was some kind of magician by levitating ...

Ever wanted to levitate a can or bottle inside an illuminated ring? Of course you have. Well, this device from Chinavasion uses the force to do just that. Unfortunately it uses force of the magnetic ...
