Larmor equation

An MRI term for a formula for which the frequency of precession of the nuclear magnetic moment is directly proportional to the product of the magnetic field strength (Bo) and the gyromagnetic ratio (g), as in the equation, å = g x Bo.

by adding a Rayleigh dissipation function to the Lagrangian which describes the Larmor precession of the magnetic moment.
Three transformations create a coordinate system, which rotates as dictated by free Larmor precession in the rotating field.
[B.sub.0] reverses the direction of the Larmor precession and
order because the Larmor precession that they induce is approximately
There are inevitably stray fields within the "zero-field" gaps that give rise to unwanted Larmor precession around the local stray field direction.
The fields are oriented in the correct sense in this case so that no [pi]-flipper is required between the two arms of the spectrometer as in a conventional (longitudinal field) NSE instrument; consequently Larmor precession occurs within the coil length in opposite directions on each side of the sample.
For the cancellation of the Larmor precession with the pseudomagnetic precession, we need to know the value of the pseudomagnetic field.
In fact, the presence of two species undergoing Larmor precession makes available a wide range of double resonance techniques, well known from NMR practice.
The observed visibility of the interference between upward and downward spin components perpendicular to the Larmor precession plane of the neutron spin are compared with the numerical simulations in the plane wave theory and also in the Schrodinger wave-packet model.
The aim of Romalis' project, "A Test of CPT Symmetry Using a New [K-.sup.3] He Self-Compensating Magnetometer," is to perform a high-precision test of combined charge conjugation, parity inversion, and time reversal (CPT) invariance and local Lorentz invariance by comparing the Larmor precession frequencies of potassium (K) and helium 3 ([He.sup.3]) atoms in the same cell as a function of time, i.e., the daily rotation of the Earth about its axis and the movement of the Earth relative to the cosmic microwave background radiation.
