Spin-rotation relaxation. As a molecule or a part of a molecule rotates about a nucleus, the motion of electrons generates a current and a molecular magnetic moment. 1, record 2, English, - spin%2Drotation%20relaxation

Spin Rotation Relaxation : A molecule in a fluid medium is a charged system and therefore generates a magnetic moment apart from the nuclear moment. Collisions change the rotation rate and causes the field to fluctuate which aids in relaxation. 2, record 2, English, - spin%2Drotation%20relaxation

The fundamental parameters of the NMR [nuclear magnetic resonance] gyro are defined in the following manner : The signal-to-noise ratio is a parameter which characterizes the noise-induced random drift and the ability to determine drift angle in the NMR gyro. The relaxation times characterize the fundamental usefulness of the resonance cell. Finally, the rate bias instability characterizes the shifts in the precessional frequency of the macroscopic magnetic moment. 1, record 3, English, - noise%2Dinduced%20random%20drift

The nuclear magnetic resonance(NMR) gyroscope is a rate-integrating, single-axis gyro that obtains its rotational information from the dynamic angular motion of certain nuclei... The NMR gyro utilizes the intrinsic property of certain nuclei to determine angular displacement about a defined input axis. These nuclei have angular momentum, hence magnetic moment. 5, record 4, English, - magnetic%20moment

Le principe de la résonance magnétique repose sur le fait que lorsqu'un moment magnétique situé dans un champ magnétique est soumis à une excitation magnétique périodique, son comportement n'est influencé par l'excitation que si celle-ci à une fréquence bien déterminée. Cette perturbation affecte le comportement électromagnétique de l'échantillon étudié et peut être mesurée. On obtient alors une courbe de variation appelée raie de résonance. La mesure directe de la résonance magnétique a été améliorée à l'occasion des études sur les radars pendant la Seconde Guerre mondiale. 6, record 4, French, - moment%20magn%C3%A9tique

Lévitation magnétique [...] - rotation: il est possible de faire léviter un objet avec des aimants fixes. Un exemple en est le lévitron : il s'agit d'une toupie aimantée qui est en lévitation au-dessus d'une base aimantée. En fait, le lévitron peut être considéré comme une sorte de corps diamagnétique : par rotation, on stabilise la direction du moment magnétique dans l'espace (on a un gyroscope magnétique) et on place cet aimant dans un champ magnétique anti-parallèle. 7, record 4, French, - moment%20magn%C3%A9tique
