The domain theory of ferromagnetism is a theory that explains how ferromagnetic materials have permanent magnetic properties. The theory states that ferromagnetic materials are made up of many tiny regions called domains, each of which spontaneously magnetizes. The domains are free to move among the regions, and the direction of spontaneous magnetization varies from domain to domain. #snsinstit...

Ferromagnetic materials are strongly attracted to both poles of magnets. Paramagnetic materials are weakly attracted to a single pole. Diamagnetic materials are the most unique of these three types, as they repel both poles of magnets. #snsinstitutions #snsdesignthinkers #designthinking

In 1913, values of angular momentum and magnetic moment were obtained by Bohr. In 1920, Wolfgang Pauli gave it the name Bohr Magneton. Bohr magneton is a physical constant value and it is the magnetic moment of an electron due to its angular momentum and also orbital momentum. #snsinstitutions #snsdesignthinkers #designthinking

#snsinstitutions #snsdesignthinkers #designthinking Lasers are classified into many types based on the medium used in them, the pumping mechanism, or their applications.

#snsinstitutions #snsdesignthinkers #designthinking Einstein coefficients are mathematical quantities that describe the probability of an atom or molecule absorbing or emitting a photon. They are named after Albert Einstein, who proposed them in 1916.

#snsinstitutions #snsdesignthinkers #designthinking Spontaneous emission and stimulated emission are both processes that involve an atom changing energy levels, but they differ in how the atom is stimulated and the properties of the emitted photons
