In this letter, we study energy-preserving (EP) splitting methods for solving charged-particle dynamics in a normal or strong magnetic field. Two novel EP splitting methods are formulated, and their energy-preserving property and accuracy are analysed. A numerical experiment is carried out to demonstrate the error and energy behaviour of the splitting methods.
