where is the torque, is the angular momentum vector, is the external magnetic field, is the cross product, and is the gyromagnetic ratio which gives the proportionality constant between the magnetic moment and the angular momentum. The angular momentum vector precesses about the external field axis with an angular frequency known as the Larmor frequency,
A famous 1935 paper published by Lev Landau and Evgeny Lifshitz predicted the existence of ferromagnetic resonance of the Larmor precession, which was verified experimentally and independently by J. H. E. Griffiths (UK) and E. K. Zavoiskij (USSR) in 1946.
Larmor precession is important in nuclear magnetic resonance.
