In view of the phenomenon in the magnetic mechanical oscillator model,Hook's law and Maxwell's equation are used to establish the second order ordinary differential equation and obtain the factors affecting the amplitude and energy of the spring sheet.The control single variable method was used for experimental exploration,and then the experimental video was tracked frame by frame by Matlab simulation and Tracker software,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 experimental method for the related research of magnetic mechanical oscillator.
