If you made a motor out of a magnet, a wire coil, and some needles, you probably remember that motors and generators depend on a rotating magnetic field. Once you know how it works, the concept is … ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Rotating the magnetic field at specific speeds separates only particles of certain sizes, ... A short animation of the process is available at: ...

In essence, a rotating magnetic field is employed to visually identify, within a dissociated tissue preparation, cells that contain magnetic material by their rotational behavior.

Lightning strikes are caused by the SUN: Rotating solar magnetic fields pull electric storms towards Earth. University of Reading study says the sun is increasing Earth's lightning ...

Microscopic magnetic particles driven by rotating fields exhibit spontaneous edge currents, with particles at the boundaries moving faster than those in the center.

VIDEO * This animation demonstrates a technique that uses a magnetic field to selectively separate tiny magnetic particles using an array of metal disks, representing a highly sensitive method for ...
