The time evolution of the magnetization of an ensemble of magnetic moments in a magnetic field is described by the Bloch equations,
Inserting into the Bloch equations yields
In the Demonstration, we set , so all frequencies and relaxation rates are expressed in units of . The time unit is therefore and the total time is equivalent to the number of Larmor cycles.
