{wiki=Bloch_equations}
The Bloch equations are a set of differential equations that describe the dynamics of nuclear magnetization under the influence of external magnetic fields, specifically in the context of nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI). They provide a mathematical framework for understanding how spins of particles like nuclei evolve over time due to applied magnetic fields and interactions.
