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.
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 ...
Astigmation controls are both magnetic and electronic (dynamic); magnetic does most of the work while electronic is used for fine adjustments. [252] One of the ends of the electron gun has a glass disk, the edges of which are fused with the edge of the neck of the CRT, possibly using frit ; [ 253 ] the metal leads that connect the electron gun ...

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.
View of a frame-maker's workshop, oil on canvas, circa 1900 The elaborate decoration on this frame may be made by adhering molded plaster pieces to the wood base.. A picture frame is a container that borders the perimeter of a picture, and is used for the protection, display, and visual appreciation of objects and imagery such as photographs, canvas paintings, drawings and prints, posters ...
