摘要	In this paper, we construct a kind of explicit square-conservation scheme for the Non Damping Landan-Lifschitz(LL) equation. The basic idea is to semidiscrete the Non Damping LL equation into the form dy/dt=A(t, y)y, A(t, y) is skew symmetry, then we apply Magnus methods to the form. It can preserve the square conservation property of the equations. We give some numerical results of the Non Damping LL equation.
