One hundred years have passed since the discovery of superconductivity. Over this time, the science, especially in the area of physics, relating to superconductivity has improved dramatically. However, no appreciable progress has been made in the education of superconductivity in relation to primary electromagnetism. A superconductor is a unique material in which Ohm's law is not applicable to the flow of electric current. If this physical point is carefully considered, a new perspective on electromagnetic properties emerges. In this series of lectures, electromagnetic phenomena in superconductors are examined from various aspects. The first lecture deals primarily with the magnetic phenomena occurring in the vicinity of superconductors while they are in the Meissner-Ochsenfeld state, showing perfect diamagnetism. It is shown that by introducing this magnetic phenomenon to the present E-B analogy, the style of teaching primary electromagnetism can be dramatically changed. In accordance with this analogy, it would even have been possible to predict the existence of superconductors in the 19th century after the formulation of the Maxwell theory. This kind of discussion reinforces the E-B analogy. The introduction of superconductivity makes it possible to directly derive the magnetic energy through a mechanical action working against the magnetic force. In contrast, the magnetic energy can be derived only after teaching electromagnetic induction in existing textbooks. Other merits of introducing superconductivity are also discussed.
