An electric current generates a magnetic field, which can be regarded as the superposition of the magnetic fields produced by positive and negative charges moving in a specific direction within a conductor. In traditional electromagnetic theory, the magnetic fields generated by different moving sources are directly superimposed vectorially; however, this approach may have certain limitations at the microscopic scale and under specific conditions. This paper adopts the analytical framework of classical electromagnetic theory to simplify and reconstruct electromagnetic interactions, proposing the mechanism of the “field-strengthening rule.” This mechanism may yield more consistent computational results in certain scenarios. The article presents some hypotheses regarding gravity and proposals for testing antigravity, as well as ideas that go even further against our physical intuition.
