When an energetic electron with a certain spin is injected into a ferromagnet – such as iron, cobalt or nickel – the spin on the electron partially aligns itself with the magnetic field. This means ...
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 ...
