Cool frames, right? Actually, this is the "confetti top," one of dozens of magnetic clip-ons you can add to any Pair Eyewear glasses. (Photo: Pair)
The energy diagram of the transitions between the ground state and the magnetic state. Solid arrows represent absorption of photons and dashed arrows represent non radiative processes Photomagnetism ( photomagnetic effect ) is the effect in which a material acquires (and in some cases loses) its ferromagnetic properties in response to light.
Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other.Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism.
Under the proper circumstances, the photon's magnetic fields effect is as strong as their electric field – as e.g. in solar cells. The discovery is a surprise, because it is not straightforward to derive the strong magnetic effect from the physical equations, and thereby indicate that this quantum mechanical effect would be interesting enough.
A magnet's magnetic moment (also called magnetic dipole moment and usually denoted μ) is a vector that characterizes the magnet's overall magnetic properties. For a bar magnet, the direction of the magnetic moment points from the magnet's south pole to its north pole, [ 15 ] and the magnitude relates to how strong and how far apart these poles ...
Magnets exert forces and torques on each other through the interaction of their magnetic fields.The forces of attraction and repulsion are a result of these interactions. The magnetic field of each magnet is due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the mater
