Description : EE6302 - Electromagnetic Theory - Lecture Notes
UNIT – 1 Electrostatics - I
Electromagnetic theory is a discipline concerned with the study of charges at rest and in motion. Electromagnetic principles are fundamental to the study of electrical engineering and physics. Electromagnetic theory is also indispensable to the understanding, analysis and design of various electrical, electromechanical and electronic systems. Some of the branches of study where electromagnetic principles find application are:
RF communication, Microwave Engineering, Antennas, Electrical Machines, Satellite Communication, Atomic and nuclear research ,Radar Technology, Remote sensing, EMI EMC, Quantum Electronics, VLSI ,
Electromagnetic theory is a prerequisite for a wide spectrum of studies in the field of Electrical Sciences and Physics. Electromagnetic theory can be thought of as generalization of circuit theory. There are certain situations that can be handled exclusively in terms of field theory. In electromagnetic theory, the quantities involved can be categorized as source quantities and field quantities. Source of electromagnetic field is electric charges: either at rest or in motion. However an electromagnetic field may cause a redistribution of charges that in turn change the field and hence the separation of cause and effect is not always visible.
Sources of EMF:
-> Current carrying conductors.
-> Mobile phones.
-> Microwave oven.
-> Computer and Television screen.
-> High voltage Power lines.
Effects of Electromagnetic fields:
-> Plants and Animals.
-> Humans.
->Electrical components.
Fields are classified as
-> Scalar field
-> Vector field.
