4.1.2 Origin of Magnetic Dipoles - Technische Fakultät

The electron magnetic moment is intrinsically connected to electron spin and was first hypothesized during the early models of the atom in the early twentieth century. The first to introduce the idea of electron spin was Arthur Compton in his 1921 paper on investigations of ferromagnetic substances with X-rays. In Compton's article, he wrote: "Perhaps the most natural, and certainly the most generally accepted view of the nature of the elementary magnet, is that t… WebMagnetic moment (μ) of a system arises from spin unbalance between spin-up and -down levels.

Contributions due to the sources of the first kind can be calculated from knowing the distribution of all the electric currents (or, alternatively, of all the electric charges and their velocities) inside th…

Webfield, there will be a force induced on the magnetic dipole moment of each atom despite the atom being neutral: F B zzz = ∂ ∂ μ where the field gradient is chosen to lie along the z-axis. We thus expect to see the beam deflect depending on the value of μz. If the magnetic dipole moment is directed up ( 0μz > ), then the force is up. If ... WebJul 26, 2011 · The RF field causes the nuclear magnetic moment to precess about the z axis in a spiral. After a time, the moment is located in the x-y or transverse plane, and B1 is typically turned off (this is a 90 degree pulse). The moment continues rotating at the Larmor frequency in the transverse plane until losses "relax" it back to +z.
