In view of the phenomenon in the magnetic mechanical oscillator model, Hook's law and Maxwell’ sequation are used to establish the second order ordinary differential equation and obtain the faetors affecting theamplitude and energy of the spring sheet. The control single variable method was used for experimentalexploration , and then the experimental video was tracked frame by frame by Matlab simulation and Trackeisoltware, and compared the experimental results and theory. The average relative errors of the five groups were 3.21%,1.83%,2.67%, 1.98% and 2.36% , respectively, which provided theoretical support and experimentalmethod for the related research of magnetic mechanical oscillator.
