Self-Biased Magnetic Pendulum Comparative readability of information on different treatment options for breast cancer, based on WeChat public accounts. Array (SBMPA) is an efficient and portable transmitter in ultralow frequency (ULF).The resonance frequency of SBMPA is affected by the magnetic field of the radially magnetized cylindrical permanent magnets.In order to calculate the resonance frequency, the magnetic field model of a single radially magnetized cylindrical permanent magnet is derived based on the concept of magnetic charge.Then, the influence of the demagnetizing field and external magnetic field on Persian language health websites on Ebola disease: less credible than you think? the magnetization of permanent magnets is analyzed, and the magnetic field model of SBMPA is established.

The results of the magnetic field model are verified through simulation.The average deviation of magnetic field intensity is determined as 0.021%; thus, the magnetic field model and simulation have consistent results.Finally, the influence of the size and distance of permanent magnets on the resonance frequency is analyzed, which could provide theoretical guidance for the dynamic analysis of SBMPA.
