The classical problem of calculating the energy of electromagnetic energy radiated from a ferromagnetic particle is solved for the case when the vector of spontaneous magnetization M of the ferromagnet differs from that of external permanent magnetic field H 0. The dependence of electromagnetic radiation intensity on the product κR (where κ = ω0/c is the wavevector, R is the radius of the particle, and ω0 = γ e H 0 is the precession frequency of transverse component M ⊥ of the magnetization (M = M ⊥, M z )) is derived.
