In the world of particle physics, you are never alone — quite literally. Every moment there is an invisible rainstorm of subatomic particles falling down on us from space. Unlike the kind of matter we ...

Current textbooks often refer to the Lorentz-Maxwell force governed by the electric charge. But they rarely refer to the extension of that theory required to explain the magnetic force on a point ...

Magnetic separation has become increasingly popular in biomedical science and industry. This technology uses magnetic properties of micro/nano-sized particles to separate macromolecules of interest, ...

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 ...
