A new electromagnetism is still expected to be developed. Thus, under such a principle where nature works as a group, an electromagnetism beyond Maxwell is studied. It considers that light metric antecedes electric charge for founding the EM phenomena. Based on wholeness principle, Lorentz group and gauge invariance this electromagnetism sticked on light is proposed. Then, by electromagnetism it will be understood the physics derived from Lorentz group potential fields family (for simplicity other fields are not included). New electromagnetic fields, sectors, layers and regimes are developed. It yields a branch with transversal and longitudinal EM fields, granular and collective sectors, I-fields layers and four regimes (photonic, massive,n...
