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 ...

Magnetic levitation sounds like a magic trick, but it’s pure science. Objects can be made to “levitate” by using the repelling power of the opposite poles of magnets. By applying forward motion, the ...

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 ...

An 18-year-old student has designed a 'levitating lightbulb', which requires no cables, wires or support to light up a room. Student Chris Rieger, who is currently studying electrical engineering at ...

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 ...
