The Cordus conjecture is extended to create a conceptual model for electromagnetic fields. The resulting model shows how a cordus particuloid generates small transient units of force at the sub-atomic level, thereby creating the apparently smooth and continuous electric field that we more commonly perceive. Cordus also reconceptualises how magnetism is generated at the sub-atomic level, and likewise explains how the granularity arises. It is shown that the electric field cannot be shielded, only neutralised. Cordus electromagnetism is applied to explain the electric field surrounding a wire carrying current, the locus of moving test charges in a magnetic field, and the mechanism for how force arises in permanent magnets. The contribution made by this paper is a description of electromagnetism that goes to the next deeper level: it explains the underlying mechanisms for how the forces arise. Also, it provides a mechanism for fields to be granular and directional at the small scale, but smooth and continuous at larger scale.
