2005年9月25日 · The gyromagnetic ratio is the ratio of the magnetic dipole moment to the angular momentum. I really don't get how the fact that the gyromagnetic ratio of a rotating circular loop of mass M and charge Q is g = Q/2M implies that the gyromagnetic ratio of a uniform rotating spere is also g = Q/2M!

2006年5月28日 · The gyromagnetic ratio is an important constant in many areas of physics, such as nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI). It also helps us understand the behavior of particles in a magnetic field …

2008年3月1日 · The gyromagnetic mooment of quarks depends on the model of a quark, which is still open for speculation. For point, Dirac-like quarks the gyromagnetic ratio would equal 2, with the same type of small correction like that for an electron or muon.

2008年11月3日 · Gyromagnetic ratio Ratio In summary, we discussed the gyromagnetic ratio of a thin uniform ring rotating about its axis, finding it to be Q/2M. We then applied this to a uniform spinning sphere, decomposing it into infinitesimal rings and finding the ratio to still be Q/2M.

2009年1月28日 · There is a very nice discussion of a naive model of electron spin, and the gyromagnetic ratio in Peebles Quantum Mechanics , pages 198-201. The g-factor was introduced by Goudsmit and Uhlenbeck to account for the behavior of an electron in a magnetic field because naive models of the electron do not give the proper magnetic dipole moment. g is ...

2017年11月2日 · The electron gyromagnetic ratio, also known as the g-factor or the Landé g-factor, is a dimensionless quantity that describes the magnetic moment of an electron in relation to its angular momentum. It is approximately equal to 2, indicating that the electron behaves like a spinning charged particle. How is the electron gyromagnetic ratio measured?

2007年1月21日 · It does have a measurable effect. The sign of the gyromagnetic ratio determines the direction with which the spin precesses in a magnetic field. If the spin is used as a gyroscope to determine the rotation rate of the apparatus, then the sign of the frequency shift depends on the sign of the gyromagnetic ratio.

2010年6月14日 · The gyromagnetic ratio of mesons can be calculated using the equation μ = gq/2m, where μ is the magnetic moment, g is the gyromagnetic ratio, q is the charge of the particle, and m is its mass. What factors affect the gyromagnetic ratio of mesons? The gyromagnetic ratio of mesons is affected by the mass, charge, and spin of the particle.

2016年10月31日 · The magnetisation M0 of 1H is therefore also greater than 13C in the same external magnetic field, and can be calculated by dividing the gyromagnetic ratio of 1H by 13C. Other relevant factors to consider are the scaling with Larmor frequency and number density.

2014年2月23日 · Homework Statement So, we can presumably write that m = g L, where L is the angular momentum, g the ratio wanted, and m magnetic dipole moment of an axially symmetric body. Total mass is M, total charge Q, mass density \\rho_m(r)=\\frac{M}{Q}\\rho_e(r), where \\rho_e(r) is charge density...
