A new model for describing black holes based on the essential relationship between electric field and gravitational field analysis

Einstein aimed to find a unified theoretical model to explain various interactions in nature, and the relationship between gravitational and electric fields was particularly important. For the first time, this paper provides the internal relationship equations of the electric and magnetic fields. Further, the relationship between the magnetic and gravity fields is analyzed, and the relationship equations of the electric, magnetic, and gravity fields are established. On this basis, a general formula for calculating the radius of charged particles is derived. Simultaneously, we also discussed and made predictions on black holes, providing convenience for future research and experimental detection.
