We investigate the entanglement dynamics of magnons in a ferromagnet by using the entanglement criterion proposed by Duan et al. [Phys. Rev. Lett. 84 (2000) 2722]. We show that the entanglement occurs periodically with time, and discuss the effect of the external field on the magnon entangled states
