In terms of the theory of electromagnetic field, the distribution of the magnetic field, the distribution and the measure of the eddy current are analyzed when the lineal electromagnetic eddy current braking is used in the braking of high speed trains. According to the relation of the energy, the paper figures out the measure of the braking force together with the relation between the braking force and the train speed. The mechanism and the electric structure, the principles and the characters of the software and the hardware are illustrated. Finally, with the results, the measure of the braking force , as well as the relation between the braking force and the speed are validated.
