I. Definition

Electromagnetism is the unified force encompassing both electricity and magnetism as different manifestations of the same fundamental interaction. It governs how charged particles interact through electric fields and magnetic fields, and how these interactions propagate as waves — most notably, light.

II. Foundational Components

1. Charge – The source of electromagnetic interaction; positive and negative polarities create electric fields.
2. Electric Fields (E) – Vector fields produced by charges; influence other charges at a distance.
3. Magnetic Fields (B) – Produced by moving charges (currents); influence other moving charges.
4. Maxwell’s Equations – The four elegant field equations unifying electricity and magnetism into a dynamic system:
   • Gauss’s Law (Electric)
   • Gauss’s Law for Magnetism (no magnetic monopoles)
   • Faraday’s Law (Induction)
   • Ampère-Maxwell Law (Magnetism from currents & changing E-fields)

---

III. Symbolic Encoding

• E (Electric field)
• B (Magnetic field)
• ∇·E = ρ/ε₀ (Gauss’s Law for Electricity)
• ∇·B = 0 (No magnetic monopoles)
• ∇×E = -∂B/∂t (Faraday’s Law)
• ∇×B = μ₀J + μ₀ε₀ ∂E/∂t (Ampère’s Law with Maxwell’s correction)

IV. Syntactic Structure

• Prefix: “Electro-” (Greek: ēlektron = amber, linked to static electricity)
• Root: “Magnet” (Greek: magnēs lithos = Magnesian stone, lodestone)
• Suffix: “-ism” (abstract noun-forming suffix denoting a system or principle)

The term fuses etymological charge with systemic function.

V. Semantic Scope

• Powers light, radio waves, microwaves, and the entire EM spectrum
• Fundamental to electronics, communication, motors, generators, and magnetospheres
• Defines field propagation, wave-particle duality, and the relativistic union of space and time in fields

---

VI. Pragmatic Applications

• Power Systems – Generation and transmission of electricity via electromagnetic induction
• Information Systems – EM wave-based data transmission, e.g., wireless, fiber optics
• Medical Imaging – MRI (Magnetic Resonance Imaging) relies on precise EM field manipulation
• Quantum Electrodynamics (QED) – The quantum theory of electromagnetic interaction

VII. Graphenic and Logemic Signature

• Graphenic Core: “ELECTRO-MAGNET-ISM” spelled in morphemic linkage
• Logemic Function: Language of connection — electricity binds the particle to potential, magnetism shapes its path
