Bloch equations 

https://doi.org/10.1351/goldbook.08314
Set of coupled differential equations which can be used to describe the behaviour of a magnetization vector under any conditions.
Note:
When properly integrated, Bloch equations yield X′, Y′, and Z′ components of magnetization within the rotating frame of reference as a function of time.
