Magnetic Monopoles and the Quantum Theory of Magnetism in Matter

We derive the equations of quantum electrodynamics (QED) from the well known equations of classical electrodynamics (CED) of James Clarke Maxwell. The application of these equations to the solution of the old problem of magnetic monopoles reveals the existence in nature of an entity we call Ampere electron. Ampere electron has similar physical properties as Dirac electron but structurally and dynamically distinct from it (Dirac electron is the source of dia- and para- magnetism and Ampere electron is the source of ferromagnetism). The solution of the magnetic monopole problem enables us to solve two ancient fundamental problems, namely. 1. The quantum theory of magnetism in matter ( Ampere's problem, 19C) and 2. The source of the Earth's magnetic field (a fortiori the source of the magnetic fields of stars). In this paper we discuss the first problem, i.e. the quantum theory of magnetism in matter.
