Quantum electrodynamics is a part of modern physics that deals with the study of dynamic interaction between electrical force and magnetic force. In that sense quantum electrodynamics is the study of electromagnetism.
Additionally, quantum electrodynamics is nothing but a quantum theory concerned with electromagnetic force. Hence, first have to be familiar with the conception of electromagnetic force as well as electromagnetism.
An experimental result that is called Lamb Shift, allows scientists to predict about the conception of quantum electrodynamics. What is Lamb Shift? Lamb Shift is a deviation of energy level of atom or ion with the effect of quantum nature of electromagnetic field. The visual evidence of Lamb Shift is the shifting of the spectral line with the effect.
Electromagnetism
Magnetic field, electrical field, charged particles and electrical current all of these separate phenomenon have unique behaviour and characteristics. But yet all of these phenomenon in physics are closely related with each other in such an way that any kinds of changes of the any one of the phenomenon significantly results on other to changes.
Electromagnetism is a modern part of modern physics that deals with the the study of electric charged particles, electric current, electric field and magnetic field and interaction among these variables.
With the development of modern physics, electromagnetism got a modern form that is called quantum electrodynamics. But the journey of electromagnetism toward quantum electrodynamics was not easier movement. Electromagnetism have to pass through a complex way of development of physics theorem.
Previous turning point of development of electromagnetism toward quantum electrodynamics is Relativistic quantum theory of electromagnetism. When, in 1928, scientist Paul Dirac published Relativistic quantum theory of electromagnetism that in next time leads to establishment of quantum electrodynamics.
Quantum field theory is also called as a quantum theory of electromagnetic force. In 1940, scientist Feynman established a diagram which is called Feynman diagram. Feynman diagram shows that electromagnetic force is an interaction among the interacting particles.
The particles that contains electric charge produces electric field. Again electric field can exerts a force on the particles that contains electric charges. Due to the effect of electric field on charged particles, electric charge starts to move. Hence, current flow starts. Not only that. With this effect produces magnetic field.

How electric field and magnetic field interacts?
The particles that contains electric charge produces electric field. Again electric field can exerts a force on the particles that contains electric charges. Due to the effect of electric field on charged particles, electric charge starts to move. Hence, current flow starts. Not only that. With this effect produces magnetic field.
